From the user dashboard, select the Events icon.
You will then need to go to Active Event.
Select the event you want to cancel.
Select the Cancel Attendance button.
You have now cancelled your attendance.
Please Note
Not all events are set to allow cancellations and some events may have a cut off date, after which users are unable to cancel their attendance, for example, if it is close to the date on which the event is due to take place.
If the Cancel Attendance button is not showing for your event, you are unable to cancel your attendance.
