How is reputation (green bars) calculated? I searched the forums and re-read the rules to make sure this post wasn't going to be a party foul. It seems to me that some users have much more reputation then others with less of just about everything and vice versa. Is there any rhyme or reason to this or is it based of a single thing or what have you? The only reason I ask is so I can start increasing mine more.
P.S. also, how is activity % calculated because I've been stuck on 99.6 for like 3 days now and I've been really going for that overdrive achievement.
