Registering for the Site

  registration page
• They enter a desired ID and we check the database
  to see if the ID is available
• User submits all registration information and
  they are taken to the confirmation page if
  registration was successful.

  free (may or may not be maintained across
  multiple page loads, no mechanism for securing

  submitted games
