I don't know if this idea has been mentioned yet, but I think it would be great if AO implemented a trading system like EverQuest did in their last patch. Basically it allows you to set what items you want to sell and set a price for each, so when you are afk other players can look through the items you have for sell and buy them without you ever being at your computer. This would save a tremendous amount of time most people spend selling their items as it is.
