The Review process enables you to communicate
  information about the status of generations of elements.
  Using Review, you can mark a generation to be examined
  and commented on by other team members.

  The generation can then be accepted, rejected, or the
  review canceled.  To display pending reviews, do the
  following:

  1. Pull down the View menu.
  2. Choose the Review submenu.

  You can also then pull down the View menu item again and
  choose the Restrict... menu item.  This allows you to
  restrict the information displayed by the Review View.

  You can view remarks made by other users by doing the
  following:

  1. Click on an element generation.
  2. Pull down the View menu.
  3. Pull down the Expand submenu.
  4. Choose the Children menu item.

  In the Review view, "children" are defined as the
  review comments associated with the given generation.

  Typically, a developer will replace a reservation,
  thus creating a new generation, which is then marked
  for review.  Project members examine the new generation
  and add review comments.  One developer is usually
  responsible for the generation; that developer
  assimilates the various comments and accepts or rejects
  the generation.  If the generation is rejected, the
  developer may reserve the generation to correct the
  problems, and then accept the generation.
