title: TFS task with more assignees
body: <p>What is the best way to store a task for multiple users in TFS 2010 ? I can only assign one for one task.</p>
  
  <p>(for example: when I plan a demo to all developers)</p>
  
  <p>(this is a scrum Msf Agile project, where the task is part of a user story)</p>
