determine whether a site contains material suitable for viewing by
unsupervised children we have incorporated headers generated by
the Internet Content Rating Association http://www.icra.org/. For

computers. Parents and teachers wishing to know more about the system and
how to implement it on the commoner browsers will find details on their
