Your website is a static page and will show all information added to all guests, However, Once logged in to the guest area to RSVP each guest will only be shown details of and asked to reply for the specific events they are assigned to in your guestlist. This means you can show as much or as little event detail on your live website as when guests login to RSVP they will find all the relevant information about the events they are invited to.
