Congrats! I got mine too today.
The sliver sharpie makes the signatures hard to see, and yours is signed in different places them mine- but most of the main cast did not sign mine. Here is my success and the signatures are clockwise from the top right-
Understudy Kyra Ynez Siegel
Yvette Ganier
Jennifer Morrison
Lance Chantiles-Wertz (no too sure on this one)
Tobias Segal
Aru Banks understudy
Michael Cummings
Elizabeth Franz

I don't think the "AB" is Abigail's or Alison's because they both make round "A"s and not pointed ones. I hope this helps you out a little bit.
