This is just a suggestion, but I think it would be neat to drag and drop items into chat to send them to other players. Perhaps it would be limited to only players you are friends with. I know we have the mailbox and all, but for instance, right now I am talking to a friend of mine and in my house. I'd like to send something his way but can't unless I leave my location. It is not a big problem, but it might be a fun feature and perhaps encourage people to give things away more freely.
