Hi Admins,
Don't know if this has already been discussed but would be great to have a "waiting list" function on the event.
As soon as an event is full, people can still click on a "waiting list" button instead of the RSVP one.
As soon as one people who RSVP cancels, the oldest (in terms of joining the waiting list, not age :p) person in the waiting list get automatically in and receive a mail that he/she is now part of the event and has to change his/her RSVP in case he/she doesn't want to join anymore.
The order of the people in the waiting list gives the priority for them to join the event if place becomes available.
Cheers
Yoan
