Trading with people who are offline! Just like trading with people online except it's got it's own window thingy and you don't have to be in the same town. So you put up what you want to trade, then they get on put up what they want, then if you both agree you accept done... You can check what people have offered etc... (usually better for trading agreed trades from a site like this).
They SO need to add these
