You get +1 rep power every 3 months since you joined, so that's why you have two.
So I couldn't find any good topic to post this in that isn't locked - how does the rep. power system work? I mean there are people here much more worthy than me who have 1 rep power, and I have 2...what's with it? O__o
generally you give rep to people who help with something. It's basically saying "wow that was awesome, thanks alot for doing that!" sometimes I will give it when people say something really funny, or if I see someone who helped someone else. That's just me (:
Ooo thats nice to know. I thought the only way to get rep was only when other people gave you rep and not just being a member~
