We are planning on using facebook events to send out our "invitations" mailny because last year, no one RSVP. This way, when they find out, they can just click on which ever they plan to do and not have to call me or anything. I figured this was we would atleast get a ballpark on how many are going to come. You can't really personalize it like youc an with an actual invitation but you can add pictures and things like that. Anyone else planning on using facebook?
