hi not sure if this can actually be done but I thought it mite be good to think about.
disposal signs are a very hand tool I use a lot but I was wondering if there you could make a sign like the disposal but instead of just wiping the items it sells them to the serve and pays it to the player whos name is inserted into the sign it would make quick way to clear your inventor of a variety of items instead of sell handing each item.

 

oh i get the idea was only a suggestion thx for input
