UCP claims 19,555 members, now don't get me wrong but when you chek out the member list (http://www.ultimatecarpage.com/forum/memberlist.php?) there seems to be many members that seem to have never made a post. There is about every 5th 'member' or so that seems to have never made a post.
I know that no forum could ever trace all inactive, irrelevant members. There are members dating back to april 2003 (when forum started?) that have not made any posts what so ever but (please don't take this the wrong way), maybe there could be a way for them to do some cleaning up. Can they do anything?
