AI Agents 101: How to Make ChatGPT Do Actual Work
Most people still use AI like a search box: type one question, get one answer, repeat.
But the next step is AI agents: systems that can take a goal, break it into steps, use tools, remember context, and produce useful work for a human to review.
In this beginner-friendly session, we’ll demystify what AI agents actually are — without hype or jargon. We’ll walk through practical examples of how agents can help with research, planning, writing, coding, operations, and personal productivity.
We’ll cover:
* What makes an AI “agent” instead of just a chatbot
* How agents break tasks into steps
* Where agents are genuinely useful today
* Where they fail, hallucinate, or need human review
* How to design simple AI workflows for your own work
* A live demo of an AI agent-style workflow from start to finish
No coding experience required. This is for anyone who wants to understand where AI tools are going and how to use them more effectively right now.
LOGISTICS AND PARKING:
The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks!
The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

We encourage socializing but do not permit disruptive behavior of any kind. Thank you for your continued commitment to providing a fun and welcoming space to veteran, newbie, and rookie gamers in the Columbus area.

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, February 11 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.

Unlike traditional networking events, Elevate is designed to create momentum.

Every meeting is an opportunity to build authentic connections, gain fresh perspective, and leave with a clear action step to implement before the next session.

Free in-person event: Take Control of Your Mental Health
It’s time to take control of your mental health. How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind. Find out what the reactive mind is, and in the process find yourself.
Have you ever suffered from a traumatic experience, a deep loss or been through a painful breakup? Has your ability to communicate suffered as a result? And after that, even though you "moved on" did you find that things were never quite the same? Have you ever looked at childhood photos, or reminisced your early life and wondered where that happiness and spark went?
Are your emotions out of your own control? Have you ever felt, even if you aren’t aware of it, that possibly you are getting in your own way of your happiness and success? How does this affect your self-confidence?
Find out what is at the root of all stress, anxiety, depression and self-doubt. Find out how and why you hold yourself back from achieving your goals and having the life you have dreamed of. As soon as you learn what is at the root of these unwanted conditions, you’ll see it is something you can DO something about. You will not be labeled or categorized at this MeetUp.

Stalker
Based on the novel Roadside Picnic, it is NO picnic, but rather one of the masterpieces of world cinema. Andrei Tarkovsky's 1979 Soviet sci-fi classic, recounts the expedition of a writer and professor led by a mysterious guide called "The Stalker." to a futuristic wasteland called "The Zone." Dripping with existential dread, it continually presents strange occurrences that will have us debating the meaning of what we've just viewed right through the ending.
*Stalker* (1979) can be streamed for free on HBOMax, the Criterion Channel or Kanopy. It's also available for rent on Amazon Prime and AppleTV. The Columbus Library has two copies on disc.

Take Control Of Your Life, Freedom From Negative Thoughts & Irrational Emotions
Feeling down? Sometimes depressed? Can't focus? Negativity & stress? Recent losses? Creativity in career and personal life hindered by mental blocks? Sometimes we never fully recover from traumatic experiences.
Whether it was yesterday, last week or a year ago, traumatic experiences - a loss of a loved one, losing a job, a breakup - can leave you scarred. You talk about it and feel a little better, but it never goes away. After you hang up the phone, it's still there; the sadness, the cloud, the over-thinking, the worry, the guilt. You try to focus, but you're blocked. You try to look forward into new experiences, new relationships but a cloud is hanging over you, casting a shadow on what you once considered a bright, cheerful future.
What happened to your courage? Your strength of character? You're 'why not' attitude? Whoever said 'time heals' must have had a special time machine, because after weeks, months, years, you're wondering - when exactly does that kick in? Sometimes it seems like drinking or drugs are the way to go. But they wear off, and now the problem is still there with added side effects from the drugs.
At this free local Meetup event we will talk about:
* What causes grief, anxiety and depression to become chronic.
* Is it possible to regain your joy and happiness even after traumatic experiences?
* How to break away from negativity and focus on the future
* What are the steps to take to get control of your mind and your emotions?
Learn about a safe, gentle, do-it-yourself counseling that can be done in the comfort of your own home.
Let's explore safe, effective solutions for healing from traumatic experiences.
Be sure to click on the red "Attend" button below to come to the event. We look forward to seeing you there.

CMG Gives Back: Serve Dinner at FAITH MISSION GRANT KITCHEN!
Join us as we get together to get together to help those in need at this CMG Gives Back event! We have a great little community of Movie Group friends so rather than see a movie this time, we’ll help “Create a better world” by helping serve those in need. NOTE: We’re switching it up this time and going with a DINNER shift on Mon, 7/6. Here are complete details and our plan for this event:
FAITH MISSION – GRANT KITCHEN: The Faith Mission kitchen and dining room serves residents 3 meals a day, every day of the year. For this event, our group will help prepare food, serve meals, assist residents in the dining room, wash dishes, and clean surfaces.
PLAN: We will be preparing / serving / cleaning for DINNER from 4:30 to 6:30pm and have space for a total of 7 volunteers. Please arrive at 4:20pm and wear closed-toe shoes and long pants.
LOCATION: Faith Mission – Grant Kitchen is located at 245 N. Grant Ave. Enter the kitchen at Dock 1 (in the back of the building), indicated in the attached map. On-site parking in the adjacent lot and street parking are available in the surrounding area. Below are some links / attachments with additional info/details:
IMPORTANT REMINDER: Our group will be providing all of the volunteers on this day so a firm RSVP count is essential. Please only sign up if you are certain you’ll be able to attend. If something unavoidable comes up, please try to update your RSVP no later than one week prior to the event. With few exceptions, no shows or cancelations within 1 week of the event will not be eligible for future CMG Gives Back events. I appreciate your understanding as we try to ensure the agencies have the volunteers needed to provide the essential services they provide to the vulnerable population they serve. Our Partner Agency for this event is Lutheran Social Services! A huge THANK YOU to those volunteering at this (or any of our previous or future) CMG Gives Back events!
Look forward to seeing you there, Dan
Volunteer Opportunity
Open Shelter has teamed up again with Red White and Boom! Friday, July 3rd & we are looking for volunteers to run the event’s alcohol booths. Proceeds from sales go to the Open Shelter’s organization.
There are two available shifts: 12-6p & 5-11p.
There will be an ipad-like device to process transactions in addition to cash. Everything will be in bottles or cans, so transactions should be very easy. Must be 21+.
There are multiple beverage stations along the Civic Center Bridge. The stations are covered and also have beverage trucks next to them, so volunteers can cool off in the trucks.
As far as parking, it is suggested those who are coming from the east use the Columbus Commons Garage, and those from the west use the Belle Street Garage.
Harry from the Open Shelter will be your contact.
