Sorry to sound negative but this is going to wreck for sale threads with long lists of items, as this will make it impossible to edit the original post with the list. This will result in confusion, unnecessary posts saying, "x has sold," and people asking about stuff that is already gone because it's still on the for sale list. In my case, I could no longer edit anyway because it has been too long but can an exception be made in the marketplace sub-forum?
Edit: Oops, I didn't see your input on FS threads Robin. Please disregard. Oh wait, or I can just blank out this post and make it devoid of all useful information.
