I saw yesterday you posted you are using Fotos R Fun--are you using them strictly for fun photos, or for the guestbook also? (Guests will keep one strip for themselves, the other strip goes into a guestbook where they can sign). That's what I'm looking for, but Photobooth Social was way too expensive, haven't contacted Fotos R Fun yet, and I couldn't tell from the website if it's something they do or not.
