In the admin, My Tickets: Waiting Lists adds a new screen to the My Tickets settings. On this page, you can view a list of recent waiting list requests or a list of events with requests:
From an individual event, you can view the requests on that event, and download a CSV containing the list of requests for the event.
The list of events with requests shows all events with outstanding requests that are still in the future. Events in the past are hidden.
If there are events with outstanding waiting list requests that are in the past, there will be a link available to clear old waiting lists. This will remove all data for waiting list requests on all past events.
