I think members only also, it seems that in just the short time I have been here there has been a huge increase in first time posts being a FS post, but as William said it only takes a moment to become a member so that may not make much of a difference. Okay, this may not be feasible but here goes... what if the classified section was only visible to members? That way if someone finds the forum and likes it enough for what it is (a wealth of info and great people) to join, at that point "members only" (sounds very elitist doesn't it? sorry) sections would be open/visible to them. Just a thought from a newcomer.
