I do like the idea of a "combo" thread (Mmmm, Combo pizza...
), it would make it easier perhaps. then again, it could just be more of a hassle since you would have to weed out the "For sale" and "Wanted" adds, but that might not be an issue if you could clearly see what that item is doing... and usualy somthings catches your eye or you know what your looking for so it might not be a big deal.
Any others have an opinion?
