I don't get this reputation thing... I can't see anywhere, where reputation is shown. is it in the profile? If anything... i think it should be visible in every post.
Anyway. I don't think the number of posts people make is a big deal... Sure... People can 30+ posts per day. But if they are constructive and qualitative posts, i don't see one single problem with it. Sure there goes the saying "Quality over quantity". But that doesn't mean that quantity means less quality.
It really depends on the person who posts really...
Maybe mods should be more strict around spammers and n00bs.... And if there aren't enough, have more longtime and/or responsible members get the chance to be a mod, and be part of cleaning this forum
Apparently there's a high demands for them lately.
