I thought I was being smart. I had a nice little program on my computer that kept track of my guest list complete with names, addresses, phone numbers, emails, everything. All in alphabetical order. That wasn't smart at all. A few days after I mailed out the invitiations, my computer crashed and I had to reformat. The entire guest list is GONE!!
Luckily, the invites had already been sent, but I still need the list to contact people that don't RSVP and I'll need that list when I send out Thank You cards. Biggest problem, is I don't remember who all was on the list and who wasn't. Of course, there are several that I do know were on the list and can get addresses for, but is there a tactful way to make sure that people put their address next to their name when they sign the guestbook, without making me look like a total idiot for losing the list?
