I have noticed quite a few complaints about newbies-especially very young ones- posting silly and/or redundant messages. On some boards, a poster is required to have been a member of the site for, say, 3 months before he can post to certain forums (though he can read ALL forums).
Given the above scenario, at T-Nation anyone who has been a member less than 3 months could post to the beginners forum but could not post to any of the other forums (he would only have read permission for those forums). This might not eliminate all problems with regard to certain types of posts, but I think it would go a long way towards eliminating this problem.
What do you think?
