Your resource list is great help, Camp. Maybe some members consider it the "vetted list". Might be a good idea to edit it, else people will get the wrong idea.
Sellers should at no time be vetted by the detachment staff. Sellers need to be vetted by the membership as a whole. Because just like Tony has mentioned, vetted long time sellers with a perfect track record can go AWOL at any time. And if the staff can't get involved when things go south, they shouldn't get involved when things are going north either.
