Before you trade here, or during a trade, post a topic here that says, "Your Username Refs!" So for me it would be Brando's refs! That way, when you complete a trade, the person can respond on that thread, and say +1, -1, or Neutral. +1 means that the trade went through accordingly, -1 means you got ripped, or not what was promised, and Neutral usually means the cards were a little messed up, or it took a little while longer to get there.

More will be added as information is gathered.
