You know, I've been on certain newsgroups where new users have a probationary status during which new users have to have each post approved by the mods. After they pass a certain number of posts, they are given full privileges to post, though the forums are moderated in the same manner that they here. Personally, I am not up to the task of approving each and every post made by new users. The thought seems overwhelming given the current number of mods.
I sort of like the idea of requiring new users to post a certain ammount before they can view more private forums. It would be nice to have certain forums where established members can have a reasonable expectation of privacy. I got really upset over one of the pictures that was posted recently, and wanted to post something about it in the Haven. But I ultimately didn't because I didn't want to give the troll the satisfaction of knowing that he'd upset me. Instead I discussed it with a few people over PM.
