I've spent less than 10 hours of FK, but I'm really loving the feel of it. The community is nice, the staff are nice, and I love that there are a lot of different forums to experiment with.
I think I'm gonna donate in around a week or something, I just want to know how to get rewards and things like that, I also want to know how to join groups, etc.
Q: How to gain awards?
A: You're able to obtain awards by donating and/or completing the challenges, although some awards are user-owned which means users get to pick whom get them.
Q: How to join groups?
A: Groups are user-owned. Some groups charge people koins/money/etc to join groups, as other groups make you meet certain requirements and make you fill in an application.
