Missing RSVPs

I just got one.
I suspect people will use carrier pigeons to fly them to me at the reception.

everyone we're waiting on is OOT, and we pretty much know they are all NOs with the exception of FH's aunt who we're still waiting for an answer from

at least we don't have to worry about them randomly deciding to show up -- they would all need flight/hotel. annoying that about half of FH's side didnt RSVP though

edit: my mom contacted her friends 2 days after and got answers from everyone, and i sent facebook messages to my few friends who hadn't rsvp'd
