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

Do toxic people weigh you down? Affect your happiness? How can having toxic relationships affect your Health? And moreover, how can you spot them before it’s too late?

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!

Join other experienced and aspiring agile coaches and professionals to: * develop and practice your coaching skills in a peer-to-peer environment * share current successes and challenges in your work environment and get support from each other * learn from each other, build better relationships and experiment with new ideas

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.

This event is 2:30 - 4 pm Sunday. Conversation tends toward intermediate/advanced, but everybody is welcome. If you come and don't see us right away, keep looking. We could be anywhere in the restaurant.

**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!

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.

We’re heading back to Scene75 on Friday, March 27 for a high-energy night of laser tag, mini golf, go-karts, arcade games, and whatever chaos we decide to get into.

If you missed it last time, this is your shot. 🎯 What to Expect: Laser tag battles Mini golf challenges Go-karts (for those who need speed) Arcade games & game cards You can load however much you’d like onto a game card. Most people will probably be good with $15–$30, but it’s totally up to you. This is a super casual event — show up, jump into whatever looks fun, rotate groups, and hang out. No pressure, no complicated structure. Just a solid Friday night with good people. Also… I haven’t hosted in a bit and I’m making a push to be more active again. If you’ve got ideas for future events you’d love to do, bring them. I’m all ears. Let’s run it back. 🔥
