A feature that allows members to RSVP events added to a calendar has been added. When creating an event the number of attendee's can be limited. After the limit has been reached any new RSVP's are added to a wait list. A close date can be added to not allow RSVP after that date. When RSVP'ing a member can leave comments, 255 character limit. Event Creators are RSVP moderators for their own event. This feature works on all calendars from the sites default to the individual club calendars. I'll be working the instructions for the RSVP system in to the Club Coordinator help documents currently under construction.
Yes, it's perfect for that. Go to the Calendar and create an event you will see all the options available to you.
