Disable Availability Tracking
Team administrators have the ability to disable availability tracking on individual events. When creating or editing a game or event, the Availability checkbox is located at the bottom of the event details. It is checked by default, so to disable availability on a specific event simply uncheck the box and click Save.
Alternatively, team admins can disable the entire availability feature by turning off the availability tab under Manager>Tab Manager. You can read more about managing tabs here.
