If you’re hosting an event, class or other type of gathering, it can be very important to know how many people plan to attend. The expected attendance can impact things like the location, the refreshments and even how many chairs you'll need. Those are just some of the reasons why Rock comes with an RSVP system that lets you track whether invitees actually plan on attending your function. If this brings Rock’s event registration features to mind, you’re not too far off. You already know how robust and flexible event registration features can be, but sometimes it might be a little more than you need. Group RSVP is for when you just need to know who’s coming, plain and simple.
