Jimmy V's Grill & Pub in Grandview Heights. You are responsible for your own meal/drinks. We usually don't have any agenda other than eat, drink and talk. :) If the weather is nice we will be on the back patio, otherwise we are in the cigar room. This group has been meeting every Tuesday evening for over a decade. Many attendees do not RSVP on meetup. Please don't let the small number here discourage you. Anyone/everyone is welcome to come. We'd love to have you join us. COTA bus #5 comes to W. 5th and Wyandotte Rd. And it's a minute walk to the restaurant. *** Did you know that there are atheists everywhere?!?! You may not know it, but we are! We're in your schools, diners, police force, military, government, and some are even still in your churches! So come and join us and meet other local atheists, along with agnostics, heathens, humanists, skeptics, and anyone else who's 'hell bound'! Vision: a Central Ohio that accepts atheism as a viable alternative in all areas of public and private life. Mission: grow, support, and provide community for atheists in Central Ohio. Social meetings held most Tuesdays at a local pub/restaurant at 7:00 PM (and often into the wee hours). Attendees call themselves agnostics, skeptics, humanists, non-theists, deists or even theists.

## Hey Columbus WIP peeps! ## Are you ready for an event that actually gives you what you asked for?? **\-\-\-\-\-\-** **A Small-group coaching conversations for women in product navigating growth, leadership, and career decisions.** **March 10 \| 5:30–8:00 PM** **Rev1 -- NEW SPACE** **330 Rush Alley #100** **Parking Options:** • **Rev1 at The Peninsula** • **Starling St. Garage South** – 377 W. Capital St. • **LAZ Parking (COSI)** – 50 Belle St. • **LAZ Parking Limited** – 375 W. State St. • **Veterans Memorial Lot** – 300 W. Broad St. • **Metered Street Parking** **What moves are you making?** A promotion you’re working toward. A role change you’re considering. A bigger leadership opportunity. A conversation that needs to happen. A decision that’s been sitting in the back of your mind. For our Q1 Women in Product Columbus event, we’re creating space to actually work through those moments. **Making Moves** is an evening of focused, facilitated coaching conversations with experienced mentors from our local product community. This isn’t a panel. It’s not passive networking. It’s small-group dialogue designed to be thoughtful, practical, and worth your time. Here’s how it will work: • You’ll choose a topic that reflects what you’re navigating right now • You’ll join a small coaching circle (5–7 participants) • Each circle is led by a mentor who has lived experience in that area • We’ll run two rounds so you can go deeper or explore a second conversation ### Coaching Topics: • Communicating the Value of Your Work (or Team) • Career Transitions & What’s Next • Growing Into Leadership • Staying Relevant as Technology (and AI) Changes • Getting Alignment and Decisions from Leadership Our goal is simple: you leave with clearer thinking, practical perspective, and at least one next step you feel confident about. Space in each circle will be limited to keep conversations meaningful. If this sounds like the kind of room you’ve been wanting to be in, we’d love to see you on March 10. RSVP here!

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!

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.

Private Group. Closed to the Public Knowing ourselves and understanding our abilities is the first step toward wielding our gifts with control and accuracy. In subsequent classes we will verify and hone our talents with activities and discussion. These are hands-on workshops and participation is expected. The goal of our series will be to develop expertise in areas of particular interest such as mediumship, channeling, divination, healing and, etc.. Our ultimate directions will be determined by class members as we evolve. I look forward to sharing and discovering with you. - Cynthia

The Humanist Monthly Program is our longest running event and still a community favorite. In the old days it used to be called "Going to HCCO" and we still like to think of it as our flagship event. Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Our March speakers are Molly Gaines and Zack Parrish, co-organizers of the Secular Education Association: They will share their story of how a small group of Ohio parents grew into a national organization tracking released-time religious instruction and other church–state issues in public schools. The presentation will cover SEA’s early wins and hard lessons, what we’re seeing nationally right now, and how local advocates can play a meaningful role in protecting public education. Attendees will leave with a clearer understanding of the landscape — and practical ways to get involved. Going forward our meetings will be hybrid.

**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.
