There's a topic somewhere else but at the moment I can't really be bothered to look for it.
Basically if you are mean to other users and do stuff you shouldn't you get negative karma, if you're good and get recognised for it you get positive karma.
Karma is a thing installed here that can show your behavior. Green karma means you have been very polite and helpful. Yellow, orange, and red show that you have been misbehaving. White karma means you have not broken any rules and that means you're basically perfect
You earn green karma by being polite, helpful, cooperative, and very friendly to every member whether you like them or dislike them. You get bad karma by breaking any of the TamaTalk rules.
