For example, it could be a new signature/DP, a certain card(s), more money lol, a badge, etc. Or maybe just getting to know people better!
For me, I would say it's wanting to meet more people and communicate more with the ones I already know :sakUwu:
I'd love a custom badge that shows my favorite group or bias, something fun and personal that I can display on my profile to make it feel more like mine.
My 3D Figure https://my3dfigure.com/collections/shop-all would be the coolest gift, especially if it looked like my fave idol or matched my forum avatar. I'd love to have it on my desk or shelf—it'd make this place feel even more personal. Plus, it'd be such a fun reminder of all my time spent here chatting with everyone.
