I just went back through the last 4 rounds of the swap to see who everyone (who has signed up so far) had in the past for partners. My goal is to try to pair people up with someone they haven't swapped with in the last 4 rounds. Round 4 was 2 years ago!
I also did a little "swap fishing" and posted a note in the gallery of the last 7 rounds (but not the ongoing versions) to let people know that Round 8 was happening. So, if it pops up as an unread post from way back, you'll know why
