If we can provide a front end interface to allow Event Managers the facility to manage the registration for their event, I think it would be beneficial to many administrators. Event Managers are individuals who are responsible for their organizations event(s).
The functionality that I would see being of benefit would be limited to:
* Could only see their event (Event ID in menu?);
* Could remove (delete) a registration (maybe "unpublish"?);
* Could update some basic registration details;
* Could re-send confirmation email;
* Could move a registration to/from the wait list from/to an event.
Probably good to have a recorded log of their activity!
