Waiting lists
Never miss an opportunity to fill your event; have the confidence to add capacity.
If your events are popular, or if you are restricted on the number of people you can have, you may find that you need to have a waiting list. This means that, if your event is full, people can add themselves to a waiting list. If someone drops out of your event then the person on the waiting list can be added to the list of attendees. You can require that wait-list attendees pay for their spot in line so that you can try to add more capacity to your event.
