OK, I've seen this on other websites, though not on a forum, I like the idea though. Here's how it works: you have a '-' and a '+' symbol on each persons individual post, when a post is good you hit + when it's bad you hit - if a post gets enough - hits it will be "buried" and you wont be able to see it unless you click on the "view post" link in it's place, if it gets enough + hits it will be highlighted, or maybe even featured in another part of the forum, what do you think of this idea?
