It is not the selling of specific items that is the issue. When EE was alive, this area was for trading only - not selling. It had nothing to do with Thom, or anyone else saying what could or could not be sold here. I, personally, have no problem posting an item for sale, or posting that you are looking to buy an item. I am merely stating that the rules used to be that there was to be no selling, here. That said, I, too, would appreciate an official statement from those in charge of these forums.
Please, see the, "About the Trading Post" topic in this area.
