Hi! We created e-mail invites to an upcoming event. We made a survey that serves us as RSVP-form. Its just a simple YES, NO, "Additional comments" kinda survey. Here's my question: when I send the email with the survey to someone, they RSVP and then forward the email to someone else, are those people able to RSVP to the email via the same link? OR will it direct them to the Thank You page, since the person we sent it already RSVP'd?
