Some forums have this (rep/neg) system where you can pretty much like/dislike someones comment and it adds to their reputation - best way to describe it.
You start off on Gray
If you get negged, you go Red
If you get repped, you go Green
If you get 100 points of Rep, you go 2 bars of green, 200 points, 3 bars etc etc
Would be pretty cool to have the system on here. Would probably stop a lot of name calling too if people could just neg other peoples posts.
Y'all know what I'm sayin?
