After reading that you were still waiting on swappers, I looked at the list of players to see what might still be missing. One that you don't have marked as being mailed is involved in a huge amount of groups. It affects all of my groups except for 1. I'm pretty sure it must affect everyone in the swap. Have you thought about what you want to do if you don't get the remaining groups sent in? Have you heard from the swappers? Just curious, I'm not in a hurry or anything.
