Once a class is full, 5 members can add themselves to the waitlist.
Once you are on the waitlist, if a spot opens up, you will get a text notification. On a first-come-first-serve basis, you can reserve a spot in the class. If another spot opens up you will get another text notification and opportunity to claim a reservation until you are in class and off the waitlist. This will continue until 30 minutes before class time. Being on the waitlist does not commit you to class. The waitlist is a notification system that gives you immediate notification that a spot has opened up that you can claim. Only you and the other 4 people on the waitlist will be notified.
