title: Query only work items that are assigned to me in Team foundation server
body: <p>We have projects in 3 Project Collections in TFS 2010.</p>
  
  <p>Currently, when a user runs a work item query, that user can see all work items in the projects that they have access to.  How can I restrict this so that users can only view the work items where the <code>[Assigned To]</code> field is set to them?</p>
