Shut Up & Write!® East Side Columbus
Join us for an hour of writing! We’ve discovered that it’s strikingly helpful to write with other writers. See if it’s true for you at 7:00pm on Wednesday, March 25 at Streetlight Guild.
Be it a book, blog, script, essay, dissertation, resume, melody, poem or just plain work stuff, you are invited to write it with us. No one will see what you've written or give you unsolicited advice. Instead of just thinking about writing, come and get some real writing done.
**SCHEDULE:**
6:45ish - Quick introductions
7:00 - Timer starts: write for 1 hour
8:00 - The End
**OPTIONAL SOCIALIZING** happens before and after the writing hour. Writing is very solitary. Connecting (and sometimes even commiserating) with other writers is a cool thing.
**BEING LATE IS OKAY:** just show up and get settled! If you were on time, please be willing to make room for the friendly latecomer.
Happy writing & I look forward to seeing you at Streetlight Guild!
**WHAT SHOULD I BRING?**
Whatever you need to be able to write! You're welcome to bring earplugs/headphones if noise will bother you!
**OTHER IMPORTANT DETAILS:**
* **RSVP:** Please RSVP by 6:00pm the evening of the meeting. This helps me know how many to expect, and if we'll need additional space!
* **COVID:** While masks are not required, please be mindful of the other writers around you and their comfort levels.
* **WIFI/OUTLETS:** Outlets are limited, so please ensure your devices are charged when you come! But Streetlight Guild does have free WiFi! Yay!
* **PARKING:** There is free public parking at Streetlight Guild.

From Web Forms to Web Components - Burton Smith
**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you.
The building address is 4450 Bridge Park
The entrance is 6620 Mooney St, Suite 400
**Abstract**
Web Forms gave .NET developers a powerful abstraction for building reusable UI controls long before design systems were a thing. Web Components finally bring that same idea to the browser natively.
This session explores how the Web Forms mindset translates into Custom Elements, Shadow DOM, and HTML templates. We’ll examine how Web Components enable design systems that work across frameworks, how they differ from server‑driven controls, and why they’re becoming a foundational layer for modern UI. Whether you’re maintaining legacy apps or building greenfield projects, you’ll leave with a practical understanding of how to apply familiar patterns in a modern, standards‑based way.

Spring Flex Season
**How does a TennisColumbus Season / League run?**
The league advertises the season dates and builds a queue of committed players for the season.
**Kickoff Day - March 26th**
The start day of the season, players are sent a kickoff email that contains important information about the league, the link where your league standings and players contact information. We guarantee 6 playing partners at your playing level, but have been averaging closer to 15+ partners in most cities. The number of different levels we run is solely based upon the number of players enrolled for the league kickoff. Typically we are running a Skilled-3.0, Competitive-3.5 and Advanced-4.0 in most cities.
**Your Task - "Flexible Scheduling"**
After this kickoff email is sent, it is the **player's task to communicate with other players**. Players should work with their partners to find an agreeable time and location to play the match. While TennisColumbus doesn't mandate your playing schedule, it is recommended that players schedule at least one match per week. By request of the players, we started to allow players to play 1 rematch per season. The regular season is all about playing as much as you can. As of Feb. 10, 2026 we've had an amazing 2,017 players play more than [20 matches in a season](https://www.tenniscolumbus.com/info/MatchesInSeason).
**Where to Play?**
Play at your local free tennis courts, tennis parks, condo courts or tennis clubs. The league strongly suggests that players jointly try to pick a tennis court location convenient to both. We provide an extensive list of [tennis courts](https://www.tenniscolumbus.com/TennisCourts), including # of courts, lighting, hitting walls, etc. We strive to keep this list up-to-date.
TennisColumbus sets up a must play dates to push players out on the courts. The final deadline is the date marking the end of the season, at which point players with 3-5 wins (Actually total is specified on the division page) will qualify for a post-season playoff to determine the league champion.
**How to Play?**
Players can use three mostly standard playing formats: 2 out of 3 sets, 2 sets with 10 point super tie-breaker or the 10-game pro set (First to 10, used when court time is limited). On Feb. 2018, we added Fast Tennis 4 game pro set format as a valid format.
**Playoffs**
Each season concludes with a playoffs where players with anywhere from 3 to 5 season wins qualifies for a single elimination tourney. The champion is awarded based upon the league [Prize Pool](https://www.tenniscolumbus.com/info/prize_pool3). Each singles league champion also receives a playing entry into one of two national championships we run.
**[JOIN TODAY](https://www.tenniscolumbus.com/join)**
Full price is $39.95 to play in a season. The earlier you sign up we typically offer discounts during these tough economic times. Just go to the [Join Page](https://www.tenniscolumbus.com/join) and complete the short form. We'd be happy to find you dedicated tennis playing partners.

Long Form Night - Columbus Comedy Improv Meetup at Gresso's!
Whether you've never done improv before, or you've done it for so long you knew Del Close on a personal level, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup** for some fun and games! Tonight's a special one; this is "Long form" night!
Most nights here at Improv Meetup, we play "short form" games, where the host has established rules that the players must adhere to. These scenes frequently do not tell a connected story and are focused on following those rules; games such as "Alphabet Game" where every next sentence needs to start with the next letter of the alphabet, or "Interrogation" where it's a guessing game.
Tonight is focused on "long form", where we will see groups of people come up and do a sort of improvised play. There may be rules to the structure itself to adhere to, or it may be more free form, but doing this allows players to establish a shared world, and to establish characters and callbacks. While your average game may last 2-3 minutes, a long form set will last much longer, and have 4+ people involved. This may be a more complicated night, but we will make sure you feel supported to try this out.
Our meetup, which is central Ohio's longest running (and free!) weekly comedy event, brings the games (and occasionally different forms) for you to play in a safe, supportive, and compassionate environment. Not only is it a lot of fun, but you get to work on thinking faster on your feet, plus it's an excellent way to meet new people and make friendships that'll last a lifetime!
Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "Yes, And" that you'll have fun!
Using Philosophy to Cope with Current Events
So this month's prompt is more general. I think we can all agree that we are living in "unique" times that require coping skills. I think that one role and/or purpose of philosophy is to help us deal with our daily lives and our "unique" times. So, let's share our feelings and thoughts about which philosopher/philosophy we turn to in order to deal with our crazy events. Who/what helps you stay focused in your daily life and helps you sleep at night. I find that Stoicism with a little philosophical pessimism mixed in goes a long way in helping me deal with what I see as very destructive, fearful and mean spirited public policies at both the state and federal levels. Hope to see you on March 28th!
FREE Improv Comedy drop-in - Delaware
It's happening again!
**WHAT:**
Free Improv Drop-in. No experience needed / beginner friendly! (18+ for now; plans for a "kids and parents" drop-in are in the works)
**TIME & PLACE:**
Sunday 1:30pm - 3pm
Delaware Library - 84 E Winter St, Delaware, OH 43015
in the Community Room
**WHAT TO BRING:**
Punctuality, yourself, a good attitude, and a willingness to have fun and be a bit silly and goofy around others. That's it!
**WHAT THIS IS:**
A time for fun and exploration. We're going to do improv warm-up exercises and play silly improv games. Think of it as "dipping your toe" into improv comedy.
**WHAT THIS IS NOT:**
Deep improv training with scene work; a place of judgement or worrying what others think; a place where you're expected to know what you're doing.
Please mention in the comments if you're planning on attending or use the "attending/interested" function; it really helps me plan the class depending on the amount of people participating.
Feel free to comment / spread the word / message me if you have any questions. Thanks!
ALSO: Please don't take the amount of people marked going as the # that will be there; I post this on FB groups, Reddit, and Nextdoor, so I always have at least 3 - 6 people for games. Join us!
DoJo (Informal Python Meeting)
**New Dojo Location!**
**Knotty Pine Brewing**
1765 W 3rd Ave,
Columbus, OH 43212
We're going to try a new dojo location for a few weeks and see how it works
Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out. Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead.
We're looking for topic suggestions and people interested in presenting at our monthly meetings. To this end we've set up a survey form at [https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc](https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc)

In person peer-led support group for survivors of complex trauma
**Complex Trauma Support Group**
Our group is intended for survivors of complex trauma. If you are here, it’s likely that so much of who you are and what you have experienced in this life is actually invisible to most people––to family, society, coworkers, and the people who are around you.
We are a peer-led group of survivors creating opportunities for ourselves and others to share our experiences, share support, and build relationships in kind community together. Survivor experiences might include: child sexual abuse, incest, child trafficking, and other experiences of people living with traumatic dissociation and complex PTSD.
**What to expect at your first meeting:**
Currently, we are offering a bi-monthly in person group at 2:00pm on the first and third Sunday of the month. The only criterion for joining the group is that you are a survivor of trauma wishing to have more kindness in your own life and share kindness with others, and that you agree to practice to group’s relational agreements available for view here: https://www.kindgroups.com/agreements. Joining the group is free of charge.
We ask that new people connect with us for 30 minutes on the phone or on zoom before coming to their first group, so that we can determine together that we are a good fit.
Our meetings last approximately 90 minutes. Participants are never required to share. You’re also welcome to choose a pseudonym and you will never be asked for private information. You are welcome to leave at any time.
The kindness that survivors can share when among others who have survived similar childhood experiences is something we rarely get to experience. Time spent with others who understand even a little bit more about us is a relief. Our hope is to help ourselves and others experience that we are not alone. We wish for our efforts to be a cause of kindness in our own lives and the lives of each other.
You can read more about the groups at www.kindgroups.com.

How LLMs Like ChatGPT Actually Work and How to Build With Them
**First meetup of the Columbus AI Engineering group.**
We’ll kick things off with a practical, beginner-friendly discussion on:
**How LLMs like ChatGPT actually work — and how to build real applications with them.**
We’ll cover:
* what’s actually happening under the hood (at a high level)
* why LLMs behave the way they do (hallucinations, prompt sensitivity, etc.)
* how people are building real systems with them today
* where things break in practice
This will be a **short, informal talk (\~15–20 min)** followed by open discussion and Q&A.
Whether you’re an engineer, builder, or just curious about how modern AI systems work, you’re welcome to join.
No slides, no fluff — just real conversation about real systems.
We’ll hang out afterward and get to know each other.
Columbus Comedy Improv Meetup at Gresso's!
Whether you've never done improv before, or you've done it for so long you knew Del Close on a personal level, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup** for some fun and games!
The idea behind improv is to create entire scenes from scratch based on a suggestion from the audience. This can be done in game form, like *Whose Line Is It Anyway*, *ComedySportz*, or *Wild 'n Out*; it could also be done to tell stories, like *Middleditch and Schwartz*. Our meetup, which is central Ohio's longest running (and free!) weekly comedy event, brings the games (and occasionally different forms) for you to play in a safe, supportive, and compassionate environment. Not only is it a lot of fun, but you get to work on thinking faster on your feet, plus it's an excellent way to meet new people and make friendships that'll last a lifetime!
Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "Yes, And" that you'll have fun!
