We can definitely clean up the Classifieds / Wishlist portion of the forum. I don't necessarily see a problem with someone registering just to post a bus for sale... not everyone who owns a bus is a skoolie or has an interest in the skoolie culture, but they do know enough to think this might be a reasonable place to advertise their bus.
Of course the "Buyer Beware" caveat is always in place no matter what venue houses a purchase. I'll take some time when I get back home tomorrow and see if I can clean up some of the older stuff. If people register solely for the purpose of posting their bus, I can understand why they wouldn't come back and delete their classified post when it sells. They don't have any ties to the site... they don't care.
