title: TFS email notification
body: <p>When I add a bug (Work Item) in TFS, and assign it to a user, I want an email sent to that user.</p>
  
  <p>Also if an existing bug has the "Assigned To" changed, I want that user to get an email.
  Is it possible to send Alerts to users when they're assigned changed bugs in TFS 2008?</p>
