Since I am thinking out of the box, so to speak. I was also thinking even though I don't really know if this would be possible at all.
If there were a way to change the program, so after a prospective member have identified themselves as dealers give them a password that would only
access the Swap Forum.
That would certainly assure the continued posting of material in the Swap Forum, and at the same time prevent the dealers from stealing listing materiel for use in other venues.
