Definitely get rid of it, it is just mean. If you have a problem with someone's post then pm them or reply to their message. Plus some people seem to go overboard with the negatives and do no positives.
This is the forum of love, there is no room for negative rep!!!
Hmmm I think we should give it the flick. Its pretty crap seeing someone with a red square besides there name. Positive is all good, the negative just brings things down. If someone has beef with another forum member they should just PM the admins and mods.
I myself got a negative rep and the comment besides it says; Lol. I mean wtf?
The negative rep does need binning. You can't negative rep someone with LOL attached to it. If someone posts something good then +ive rep it, if there's something people don't like, report it.
Or if its possible, scrap the idea of showing how many total points you have, and only show overall aura under the avatar in each post eg the green squares.
