On, brainden.com, I think you should get badges when you complete a certain action. Badges would appear under your picture on your profile and on forums, under your picture aswell! For example:
Friendship Badge: Get 100 friends.
Power User: You have to go on brainden.com a lot!
Popular: Have good stats on all things.
These are just a few of my ideas, just imagine all the other badges you could make!
