In Person Event: The Secrets to Mental Health
Mental Health, how do you understand it? How can you improve it?
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.
This group is hosted by the Dianetics and Scientology Life Improvement Center of Central Ohio.

AI Freedom Alliance - Inaugural Summit
**\*\*\*\* More details and sign up at: https://aifalliance.org/summit-2026/ \*\*\*\***
**What is AI Freedom Alliance?**
AI Freedom Alliance promotes the responsible growth of AI guided by practical, commonsense ethics. Our nonprofit is built by
professionals from a wide range of industries and is made up entirely of small- and mediumbusiness representatives—never large tech companies. We provide a counterbalance to big corporate influence, focusing instead on how AI can benefit businesses and the world at large.
**What’s Happening?**
***The inaugural AI Freedom Alliance Summit.***
This full-day event will explore how we can ensure AI is adopted responsibly through shared ethical standards that empower
humanity. The summit will feature interactive and educational sessions led by thought leaders, technologists, policymakers, and advocates who are passionate about making AI fair, transparent, and beneficial for everyone.
**Why Attend?**
Learn about the legal and technical challenges with implementing AI solutions within your organization. Build better solutions while protecting your organization from legal and compliance risks. And learn how to think strategically about AI as a differentiation tool for your business.
This summit is highly recommended for C-Suite leaders to learn as well as interact with each other and our sponsors.

Spec-Driven Development with GitHub Spec-Kit - Barret Blake
**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
You will need to scan your ID at the door to get a visitor badge.
**Abstract**
*Spec-Driven Development with GitHub Spec-Kit: From Intent to Implementation*
Spec-driven development flips the traditional workflow on its head: instead of code being the source of truth, the specification becomes the backbone of design, collaboration, and delivery. In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification.
You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written.
This talk will cover:
--What spec-driven development is (and what it isn’t)
--How GitHub Spec-Kit fits into modern developer workflows
--Using specs to align product, engineering, and AI-assisted development
--Real-world examples of turning specs into implementations with confidence
Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects.

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.
This group is sponsored by the Dianetics & Scientology Life Improvement Center.

Contra dance with Big Scioty on March 7 - First Congregational Church
**Caller: Frank Buschelmann**
**Band: The Rosenthorns**
**Big Scioty Contra Dance**
**temporarily returning to our long ago location for Jan-March - First Congregational Church, 444 E. Broad St., Columbus 43215**
WHAT IS CONTRA DANCING? Picture the Grand Ball scenes like you’ve seen in period films such as “Pride and Prejudice”, where the dancers are lined up in long lines, across from each other. That’s English Country Dancing, the predecessor of contra dancing. Now, add moves like “swing your partner” and “do-si-do,” like you’ve seen in square dancing. Set it to fabulous, high energy, live music with fiddles, guitars, percussion and more, alá “Riverdance.” Finally, set the whole scene down in the middle of Woodstock, with a hip, groovy atmosphere, a bit of tie-dye, and hints of counter-culture attitude. THAT’s Contra Dancing!
Wear cool and comfortable clothes (you will get warm) and clean shoes that won't mark up our nice wood floor.
Be sure to come for the beginner's lesson from 7:30 - 8:00, followed by dancing 8:00 - 10:30. All dances are taught; we will help you learn! Beginners always welcome, no need to bring a partner.
Cost is $10.00 adults, $5.00 ages 12-26. Under 12 free. Free parking in church lot.
For more information contact me or check out our website: [www.bigscioty.com](http://www.bigscioty.com/)
Please bring your own refillable water bottle. Snacks to share are always welcome!
Oscar International Nominee: SIRAT at the Gateway Film Center
Join us as we get together to see SIRAT, an Oscar-nominated Best International Film from Spain that follows a father, accompanied by his son, goes looking for his missing daughter in North Africa. Here’s a description, trailer and our plan for this event:
DESCRIPTION: A father, accompanied by his son arrive at a rave deep in the mountains of southern Morocco while searching for his daughter who vanished months ago at one of these endless, sleepless parties. As their search continues, the journey forces them to confront their own limits. The film is directed by Oliver Laxe and stars Sergi Lopez, Bruno Nunez Arjona and Richard Bellamy.
TRAILER: https://www.youtube.com/watch?v=ww-IXHXvS70
BUZZ & ACCLAIM: SIRAT has already won numerous awards, including 4 at the 2025 Cannes Film Festival, along with the Chicago, Montclair and Toronto International Film Festivals! It also earned a whopping 11 nominations at the 40th Goya Awards, including Best Film and Director, and was nominated for Best International Feature Film and Best Sound at this year’s Academy Awards. The film is earning a stellar 92% positive rating on Rotten Tomatoes which calls it “an unforgettable exercise in tension” and “a brutal reminder that the journey can be more important than the destination.”
PLAN: We’ll plan for a 7pm-ish showing and will confirm/announce details as the date gets closer. Once showtime is confirmed, advance purchase (via GFC website preferred) is advised! Once you have your ticket, please list your seat number in the Comments section of this event.

For this event, we’ll help prepare food, serve meals, assist residents, wash dishes and clean surfaces at Fath Mission – Grant Kitchen.

Here are complete details and our plan for this event:

If something unavoidable comes up, please update your RSVP no later than one week prior to the event. With very 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.
THANK YOU: This CMG Gives Back event provides an opportunity for YOU to get involved in helping others! Benefits go well beyond the help we give to others. Volunteering provides a wide range of personal benefits, including positive effects on mental and physical health, reduced stress/depression/anxiety, increased happiness and improved purpose, life-satisfaction and personal well-being! Plus, the opportunity to get involved, connect with others and help those in need.
PARTNER AGENCY: This event is hosted by Lutheran Social Services (LSS), which serves thousands of people in need each day in 27 Ohio counties by addressing the four core societal issues of food, shelter, safety and healing. LSS offers food through the LSS Food Pantries, housing and supportive services through LSS Faith Mission and LSS Faith Mission of Fairfield County homeless shelters, domestic violence services through LSS CHOICES for Victims of Domestic Violence, senior living and health care, affordable housing communities, and other services that uplift families and strengthen communities.
Look forward to seeing you there, Dan
