Okay, maybe not totally freaking out . . . maybe just a little. We sent out our invites about 3-4 weeks ago asked for our RSVP cards to be returned by October 10. We still haven't received about half of them! Did this happen to other folks? Did you get a ton at the deadline? How many people on average did you have to follow-up with? I know everything will be fine, I'm just dreading e-mailing/calling 20+ slacker guests
