rsvpBOOK has 2 versions of the Admin Dashboard.  Which one do you have?

The Event URL is the link to your registration website. Distribute this link to your invitees. To avoid typos, always copy the URL and paste it into your marketing materials.

NOTE: If you change the Event URL after you have distributed it to invitees, the old URL will NO LONGER work.  Everyone who clicks it will receive a 404 error message in their browser window. Should this happen to you, let us know; we can create a redirect from the old to the new for you (fee applies).
