zingfit has enabled an icon with a hover feature that shows your customers when a class is on a Waitlist or Full. The little grey circle will expand to elaborate when customers hover.
Icons are configurable to display or not (hide via CSS)
The waitlist is configurable to how many people can be on a waitlist before marked full (default 20 per class)
The zingfit system will auto-enroll up to the end of the cancellation window (auto-enroll configurable) - manual enrollment after
