【IMPORTANT SUMMARY】 * The purpose of social games is to know some people, do some exercise and enjoy the games together with others. Winning and getting points is not the focus of this session. Please play with consideration to your opponents' level. * Please purchase your slot through this link [https://7538e9.myshopify.com/](https://7538e9.myshopify.com/) 【SIGN-UP SYSTEM】 * Please sign up and pay through this link. [https://7538e9.myshopify.com/products/social-game](https://7538e9.myshopify.com/products/social-game) * We don't use the signup system on Meetup.com anymore. (Neither the waiting list) * It says this event is full on this meetup page, because I didn't open any slots here for you to sign up. You have to check this [sign-up page](https://7538e9.myshopify.com/products/social-game) to see if there is still a slot available there. * The background of using an external sign-up and payment system is because Meetup.com introduced a service fee to increase 21% of the fee in May 2023, and we want to reduce this cost. 【FEE and REFUND POLICY】 * Fee includes courts and plastic shuttles. Please sign up and pay before you come. NO refund if you do not cancel until 48 hours before the event. * Racket: bring one or rent one at the counter. * You can put a comment to sell your slot after the deadline of refund, or sell your slot in our whatsapp group. * No matter the reason is sickness, accident or anything, the group or I will not afford the cost caused by your absence. * Of course you CAN'T ask me, "Can I sign up for free for next week because I didn't come to use my slot this week?". Please remember, the court booked for you was there and it costs money. The court doesn't simply become "free of charge", just because you didn't come to use it. 【COMMUNICATION】 * Communication: our whatsapp group [https://chat.whatsapp.com/JJQbJlisbcj5YDnlcSu347](https://chat.whatsapp.com/JJQbJlisbcj5YDnlcSu347) * There are too many spams, so I only accept +358 number to join whatsapp group. Numbers from other countries will all be rejected. 【OTHERS】 * Please always keep 1 meter away from those courts where people are playing. Never step into the corners of other courts! If I see you do this, I probably will yell at you! * If you have some questions, you can put your questions in the comments on the event page. People will respond. * We play double games to 21 points. After each game, please let those who are waiting to play. Feel free to play with whoever you want, but please avoid playing with the same people all the time. * If you are new to badminton, please Google basic badminton rules in advance. Serve rules, double rules and point counting rules. You are always welcome to ask anyone in our group. Most of our members are more than happy to help you. * Badminton activity is organized for non-profit purpose, but I take a small fee for my work. * Want to restring your racket? I can do restring for you. €24 including the string. Please get contact with Ken.

**Welcome to Sketchy Collective!** A relaxed and social drawing group for anyone who enjoys sketching — or just wants to give it a try. \*\*\* We meet **every Sunday at 15:00** in **Oodi Library**. \*\*\* **HOW TO FIND US** We meet on the **top floor of Oodi Library**, on the stairs **opposite** the children’s area. It's a good idea to **keep your sketchbook visible** so others can easily recognize that you're there for the sketching meetup. And if you’re a regular participant, making it clear that you're part of the sketching group can be very helpful for newcomers! \*\*\* **HOW IT WORKS** At each meetup, attendees take turns being the model for a quick **10-minute sketch session**. One person poses, everyone else sketches, then we rotate. \*\*\* **WHAT TO BRING** Pencils and paper (or any sketching tools you like). No fees, no pressure. The only thing we ask is that everyone takes a turn posing for the group. You can sit however you feel comfortable — the 10 minutes go by quickly! Draw as much as you like, skip a round if you’re tired or just want to chat, and leave whenever it suits you. The event continues as long as there’s interest. \*\*\* **STAYING CONNECTED** Due to issues with spam and advertising, the group has decided that **only people who have attended at least one meetup will be accepted into the WhatsApp group**. To be added, please ask other participants at the meetup — a few members have permission to approve new people, and at least one of them will likely be present. \*\*\* **SOCIAL MEDIA** If you’d like to share your drawings from the meetup, you can send on WhatsApp group or use the Instagram collab function (instagram.com/sketchy.collective). We warmly encourage everyone to share their work and take part in building our international sketching gallery — together with artists from all the cities where Sketchy Collective meetups are organized.

Pay attention! We’re delaying a week for those of you who may be on Spring break and/or celebrating the holiday. Ok, no pancakes, but waffles-a-plenty. Join the local UX and Digital Design community for a casual monthly breakfast. Look for us upstairs!

**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** GitHub Copilot is powerful, but what if you could scale from a solo AI assistant to an entire team of specialized agents working in parallel? 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
