While in the event overview, you can manage the participants of an event. To do so, head over to the "Participants" tab.
You can get to the participants tab in two ways:
Hover over the participant's name, then click on on the right side.
If you wish to remove participants from a large event, use the search bar. Type in a participant's name to filter your event list in real time.
Only event editors and Confluence administrators can remove participants.
