Here, you can see a list of all events defined on the currently edited site, their capacity, current numbers of registered attendees, etc.
By clicking the event name in the Event column, you get redirected to the event document's editing interface in CMS Desk -> Content -> Edit. If you click the View () icon next to an event, you get redirected to the event's editing interface where attendees can be managed. After clicking the icon in the header of the Actions column, a context menu is displayed, offering options for export of listed data to various types of files.
Detailed information about the Events module can be found in Developer's Guide -> Modules -> Events.
