Under the Instruct tab you will find a tab Events. Here you will see the events of which you are an instructor. The hat icon will show you if an event needs to be assessed. In the column with the calendar icon you will see the date of the event. Next to it you will see the amount of enrolments. If you hover over the circle in the next column, you can see if the event has been confirmed yet and if the event is still open for enrolment.
If you open the event, you can view the details. Only administrators can change the event.
