DROP-TOs 

When the @link command is used on a room, it sets a drop-to location. 
Any object dropped in the room (if it isn't STICKY) will go to that 
location. If the room is STICKY, the drop-to will be delayed until the 
last person in the room has left.  Whenever objects are dropped in a 
room, the @odrop message is displayed, to everyone in the room.
