Reputation?
 

Ive only just noticed that was there... Whats it for?

Just to see if people think your cool and crap

Like if you do a good dead OMGZ REP 4 U! Then other people look at it and there like "oh hes got alot of rep, he must be pretty nice/gay for neg rep.

Thats a cool idea. Is reputaition the green bar?

I bet people will just abuse this by negative repping someone for fun on every occasion they see.
