Run Jump-n-Play's RSVP System is a proprietary reservation system designed to aid the birthday host (usually mom but on occasions it could be dad or grandma) in his or her management of the birthday party.  Once you're set up in the Birthday Party System, the RSVP System will send you an email with a link and a code.  Simply click on the link, enter your code and you'll be able to invite your guests via email or you could print the invitation and mail them out to your guests.  Once your guests receive their invitations, they can RSVP online at that time.  You, the birthday host, can check the progress of your party by simply logging into the web address originally emailed to you when you set up the invite list.  RSVP your party or event now.
