RSVPs work the same way on team and club events. They tell the organizer who's coming, and they're visible to everyone who can see the event.

Why a reason is required
CrewLAB asks for a reason on every No so the organizer has a clear picture of who's missing and why, rather than a list of unexplained absences.
