I think you have to explain that more or else no one is going to apply. And people will think it’s a scam. (No Offense), I don’t really know if its a scam or not.
Umm actually I’m not sure I think you can just make a group with 100 Robux, never done it before, only got a group passed onto me. Before you needed Builders Club(I think) to do it but things changed a lot so not sure.
If you have a shirt or something you sell in the group the group will get group funds which are just like a bank the group has and it shows how much the group has and you can get it if you have a game in your group and people buy gamepasses from it.
You can pay if I make a shirt at the price it will cost me to make you can buy the shirt and then I will get the payment. Or you can pay using PayPal(with real money)
