This documentation is not using the current rendering mechanism and will be deleted by December 31st, 2020. The extension maintainer should switch to the new system. Details on how to use the rendering mechanism can be found here.
To enable users to unregister themselves from events (using the “my events” page), you need two things:
- Unregistration deadline: You either can set individual unregistration deadlines in the events for which unregistration should be possible, or you can set a global deadline for all events using plugin.tx_seminars.unregistrationDeadlineDaysBeforeBeginDate.
- Waiting list: By default, unregistration is only possible if an event is full and has some people on its waiting list. If you want to enable unregistration if the waiting list is empty (or if there is no waiting list), you can use plugin.tx_seminars.allowUnregistrationWithEmptyWaitingList = 1.
