a few notes about the needinfo flag which was added to bugzilla.mozilla.org last week, and enabled across all products today:

• with a few minor exceptions, it’s a normal bugzilla flag
  • searching, mail notifications, etc, all function like any other flag
  • you can use the “requests” page to search for bugs with this flag set
• if the requestee comments on the bug, the needinfo flag is automatically cleared
• you can’t set the flag to + or - .. either will result in the flag being cleared
