A pile of new postcards

You will have 1 partner, and to this partner you will send at least 10 postcards in an envelope. The postcards should be new and unwritten, not ad cards or greeting cards. Senders choice.

You need at least 20 ratings of 5 to join, and no unexplained 3's or 1's in the last 3 months. I go trough the swappers signed up when the sign up date is over, not before. No need to drop from the swap just because someone with a bad rating tries to sign up.
