I think the best way is once everyone signs up, I make groups; probably 5-6 people per group as it stands so far, I don't know maybe more.
Anyway you can make one different slide for every member of your group or you can make the same image on multiple slides. It's up to you. I don't think we'll get 36 people to sign up. I hope I am wrong.
OK, somebody lay out the details of how this all works for me, please.
