Hello there!
There is a setting in Events > Settings > Community to allow community organizers to be able to edit their events. To do this, they need to have a WordPress user account. You can read more about allowing users to register for accounts on your site here.
Organizers can view and download reports on ticket sales etc. from the events/community/list page. The links can be seen on the event in this screenshot:
Let me know if that helps, or if you have any other questions.
Thanks,
Sky
