Hi Belinda! Just sent you a private message as well
I tested your RSVP and saw all of the additional events - it worked for me! Guests will automatically see RSVP options for the events they are on the guest list for. So if you add someone to the "brunch" guest list, they will automatically see RSVP options for both "Wedding" and "brunch". Let me know if this is working for you now!
I just had to delete the extra events because for some reason weddingwire automatically added a rehearsal dinner and bridal shower event which allowed everyone to be able to RSVP to. If you go to your guest part then there should be an option to add an event and then add people to that event. To check if people can RSVP just go to your website into the RSVP section and type someone's name in and it should give the option to RSVP. Use your computer for all of this tho because I don't think you can do it through your phone. I hope this helps
