I'll put you down for XYZ, AWM (that's a lot of letters together!) if you really want it. I also don't mind doing it.
I am planning on assigning the left-right tabs. I will put those next to the letter when I list them on the signups.
Since KerTggr really wants Q, we can leave it freestanding. And if you want 2 rolodexes, you can do 2 letters. I will just ask you to wait until everyone else has a chance before signing up for the 2nd letter. I think I will leave signups open through the weekend for a single spot and open it up to a second letter on Monday. Does that seem fair?
I am not claustrophobic, so crowd away!
