good suggestion mod2k, maybe the easiest solution for now is to have someone just mod the classifieds ads and just manually DELETE the ones posted in wrong section without question.
i guess you're right, it's kinda lame to just see threads of 'bump.' 'bumpity bump' 'up to the top' and also those that post 'i'll offer 3 dollars' but i guess there's always pro's and con's.
