Okay, on this forum after traders finalize their trade with each other via private message. They will exchange address via private message as well. Then they send out their cards. Once they receive the other's cards, they will leave positive feedback, if not they can leave negative feedback or work out with each other to resolve any problem. You can't do populic blacklist here if there is something wrong with it. Since this is your first trade and you don't have 100% feedback, do you mind to send yours first?
