Description
The RSVP Events add-on adds RSVP forms to events, collecting name, e-mail, group size, custom fields, and confirmation changes made by the attendee. In Modern Events Calendar, this extension lets you configure forms per event, limit confirmations per user, block non-logged-in visitors, display remaining spots, and give the organizer a clearer view of the attendance list.
