I'd like to suggest a chat based auction that runs for 2-3 minutes. The items would be listed in a GUI menu and put into a queue to go up on a live auction. All this could be handled in an auction chat channel or the trade channel. You would be able to list multiple items at once by placing all your items into the GUI listing. When the auction is running all players have to do is type the amount they want to bid into the chat. Any bids placed in the last 5 seconds would extend the auction by 5 seconds to prevent sniping. When the auction is listed there would be a global chat announcement with something like, "Auction starting in 30 seconds: Item Name 1, Item Name, 2, etc" Why? Because it would be fun!
