If the sign-up is full or you are signing up after the cut-off date / time, use this option. Should a vacancy become available you will be contacted to fill in. If you put your name on the wait list prior to the cut-off date / time (ie because the sign-up was full) and are not contacted to play, you will automatically be put onto the sign-up for the following Sunday unless you advise that you do not intend to or can't play that week.
