NUMBERING YOUR RSVP'S?

This was big with the 06' brides and I was wondering if any of us are planning on doing it as well.

So many people said that guests sent the RSVP card back and forgot to write their name on it, so you never knew who the person was. They put a little # on the corner or back of the card, so when the card came back, they matched it to the # on the guest list and problem solved.
