There are instances where you have multiple admins and coordinators. When something unexpected changes, you may need to review who made those modifications. You may do this via the Audit Log.
Audit Logs exist for tracking group setting changes, event changes etc.,
To access the audit logs of a group you may go to "Manage -> Resources -> Audit Logs".
To access the audit logs of an event, you must login to be an admin of the event or event organizer. If you have these privileges you will see a link "Audit Log" in the Admin Panel of the event.
