Yeah that's what I was thinking at first, because they have to register a new email and everything. And then they could use a proxy, and all these other ways so I thought i'd make a little suggestion that might spark up some ideas, though I might be out of place to suggest this (since I don't know what or what not has been suggested as you mentioned above) but nevertheless; I think that maybe you should take away the General section of the forum for new members for the first month or so, or at least until they reach a certain post limit in the subject forum? Just a suggestion. Also turning off postcounts for all sections except the school/subject subforums.
