I'd like to know this too! We just use blogs and announcements to post links to Eventbrite entries. Kinda lame; would love to find a better way!
We would use these in a similar way to scheduling webinars.
But we edited the event type list in the admin console to provide more relevant (to us) options.
Generally a group would be created for a specific application, then within that group they would house their event posts. Those associated with a particular application would manage their own group rather than the enterprise community manager. (is that what you were asking?)
