It has come to my attention that because there were an odd number of people who joined the group, Elfster did an odd way of matching pairs. It's not pairs at all! You'll be receiving a gift from somepony entirely different from who you'll be sending a gift to. I hope this clears up any confusion (it sure did for me!).
Again, if you have any questions, comments, concerns, etc, let me know. Otherwise, huzzah!
