title: Removing old accounts from the Xcode Organizer
body: <p>When I open up the Xcode 4 Organizer and select Devices, and then choose a team name, I see several duplicate people on there. Some of those have a yellow warning icon which indicates they are invalid. There is no way to select them in order to delete them. </p>
  
  <p>How do I delete the extra accounts on this screen?</p>
