e-mail notification to volunteers who were volunteered by an admin

I think that it would be really great if when an admin of an event volunteered you for an event, you would automatically be sent a notification stating you were volunteered with the approprate event invormation. I believe this would be some where in the _timeslots_signup_form_submit($form_id, $form_values) function.

So, for example, let's say Mike is the administrator of the "Beer tent" event. Mike needs volunteers to run the beer tent. Mike "volunteers" Bob to run the beer tent from 2pm to 3pm. When Mike updates the event with this information, Bob would automatically recieve (or at least Mike would have the option to have the system send) an e-mail stating that Bob has been volunteered to run the beer tent on from 2pm to 3pm by Mike.

Thanks!
