We're all aware of the increasing amounts of leecher who NEVER post, or only post spam / flames, we all know those 1 rep, 0 post newbs who steal everything. Well, a solution:
Either:
Add a new rank for people with 1 rep and 10- posts
-OR-
Leave it how it is, then:
Add new forums for those people, and only allow access to them until they Either:
Get 2 Rep and 10+ posts, or get their Faded-Blue (blue-white) name, then they can access the rest of the forums, and all people could access the newb forums. A bit scrambled, but I'd recommend a new rank / title 'Newb' with a Black or Grey name that wouldn't show up to much, and trap them all in the Newb Forums until they contribute, then they can access the rest of the sections :3 (Except Elite of course, until they donate / get Contributor)
Donators are an exception, of course.
