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. All attendees are welcome but should support our vision. Atheists of Columbus (AoC) is part of Omnipresent Atheists (OA).

It was a member of Columbus CoR and held weekly meetings, mostly on Fridays, for several years but then operated as an online only group for some time. In November 2018, Omnipresent Atheists (OA), a group that routinely meets on Tuesdays, invited AoC to merge. Omnipresent Atheists is a member of the Columbus Coalition of Reason (ColumbusCoR.org).

We’re still working to get more people into these Meetups, but our goal is to give PlayYourCourt members a few social tennis outings each week in addition to your practice sessions and Challenge League matches. These Meetups are co-ed, super laid back, and all skill levels are welcome. Post your skill level and a suggested court in the comments section so we can round up as many players as we can for some tennis fun! Also, if you’re looking to meet new practice partners or play some matches and you aren’t already in the PlayYourCourt Community, you can go here to see what we’re all about and sign up: https://www.playyourcourt.com/tennis-community/columbus-oh/meetup/ If you love tennis, we’d love to have you! Be sure and watch the quick video that explains how everything works. Happy hitting! - Scott

We meet to learn and practice American Sign Language and to grow our familiarity with Deaf culture. Facilitated by hearing folks (with a connection to a professional interpreter) using Deaf-created content. People of all ASL skill levels are welcome! As we learn, we hope to connect more with the Deaf community in Central Ohio. Join us as you're able! Come regularly or just once - whatever you're looking for! Each meetup will explore different topics related to ASL/Deaf culture, and will feature time to practice conversation with one another. Just bring yourself and a willingness to learn!

While some are still meeting online, this is an in person event. Please note that we have attendees of all levels of speaking, including some native speakers. All are welcome! Also, as we meet at the same time and place each week, many don’t RSVP on the app, so we will likely have more attendees than noted here. Note: if you are asked to pay and upgrade the Meetup app, this is not necessary. You can ignore this and still attend our meetings. Find us on our [Facebook group](https://www.facebook.com/share/g/1EKw86WJCp/?mibextid=wwXIfr).

Inspired by our successful events like "Saturday Mornings @ East Market" and other "Pot Luck in the Park" lunches, this gathering promises to be a blend of fun conversations, language exchange, and cultural insights, all while sharing wonderful foods with each other. Please bring a dish to share and anything you would like to drink. We will provide plates, plastic silverware and napkins. So, come hungry and ready to chat! Note: Since the weather is unpredictable in April, we have a couple of places in mind for the Pot Luck. We have reserved a room in the Dublin Library from 1-2:30 PM for the meal, if necessary. \* But if the weather is nice on April 12th, we are planning to meet in Bridge Park, possibly in the covered shelter area at 12:00 Noon. We will update the details closer to the date of the Pot Luck but wanted to get this out to everyone so that you can make plans for that day.

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. We will be hearing from Becca Powell, Director of Advocacy and Outreach at Unchained At Last, an organization whose mission is dedication to ending forced and child marriage in the United States through direct services and systems change. Unchained At Last's mission clearly meshes and addresses several of our Humanist Ten Commitments. Becca will educate us about an issue many of us may not be familiar with--but should be. Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Going forward our meetings will be hybrid.

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD
