We send to everyone who signs up (10 so far? So we each send and receive 10 Valentines) OR I draw names and pair people up (we only send and receive 1 Valentine).
EDIT: I Tagged you in the pm. It doesn't look like I can add you as a participant. Let me know if the tag didn't help. Then I'll just put your address in the thread and send you a PM with everyone else's.
