Any interest in doing reverse consignment?  That is, someone asks for an item and provides an offer, someone else provides it.

Obviously it would be kind of difficult to get the mechanics of that sort of transaction enforced in game, however, players can still make requests and others can try to fill them.

Feel free to start threads in the respective shard forums for reverse consignment requests.  If this becomes more popular, I may create a separate system to keep track of them.
