Well, didn't find anything while doing a search for this so I don't believe anyone else has requested it.
Think we could possibly get a user reputation system going on here? I know it can be abused if people get irresponsible with it, but I've seen it do some good. Gives a small sense of reward for that encourages those to help others and can often discourage others from causing troubles.
In the few communities I've run/modded/been in I've generally seen user rep working out pretty well. Just my thought. :x
