As a user, there are three different ways of viewing and interacting with events.
If it is a stand-alone event, the user will receive an email invitation with a link to the event.
If the event is assigned through a learning path, the user will receive an email with a link to the learning path and can then choose a session from the event.
If the event is added to the explore page, then users will be able to freely search for, browse, and add themselves to events they find interesting.
All events a user has been invited to can be found on their events page, where they can also accept/decline invitations and choose sessions. If the admin labels an event as mandatory, the user will be automatically added as attending.
