Idea for groups: BADGES!
Have the option for making badges in groups. Like maybe once you like get up to a certain rank then you get a badge (if it's made)
It'll still cost 100R$ though.
I was about to support..
But think about it.
You can have a good friend that owns a group, then he ranks you up every other rank for your badge.
Plus people would be asking for rank-ups 4 times more often
