* accepts a user value both as an action parameter and as a GET parameter. The
* specified user must be an existing user. If no user parameter is specified
* or the specified user is invalid, an error message is printed. If no user parameter
* is specified or the specified user is invalid, and the current user is logged in,
* the action will display a list of pages owned by the current user.
