Wah.. another creative type @ISAIKBALULSURUR !! Great to see this post as I’m always interested in design and organising related posts! I love the idea of the passport, rundown pass and the regional flags!! Great use of the balloon sticks!!! 
Really great ideas that I hope other communities can also learn from and emulate!
When I co-organised EuroMeetup2024, we had similar gimmicks and activities to get attendees actively participating in the various events. We didn’t use the passport method but used stickers that they would win based on different challenges and they would stick the stickers on their attendee pass. You can find out more in this recap post.
Also, why no participation from Team Indonesia in the community logo/t-shirt challenge?! 
Next year for Connect’s 10th Birthday, ya!
