ok so lets get started:
1)Make a noob and turn him into a merchant account, or if you have a seller in market make him a merchant account. (5 days)
2)Make your merchant account and all of your characters trade partners. (3 days)
3)When you want to trade something with some one, simply trade the item to your merchant account and then trade it with who ever u want.
