When you purchase the Online RSVP add-on : Your guests will be able to RSVP your wedding invitation right from your wedding website. You can ask for their name, number attending (ceremony, reception, other receptions), names of those attending, their meal choice (you can even describe their choices in a pop-up box), and any comments they may have. Responses will be sent directly to you via e-mail. Totals will be sent in each e-mail to you of the number of responses, meal choices, etc.
