Protecting your family in cyberspace

In our house we just about have one computer per person. Our homeschooling approach requires this. In order to protect my family while they are surfing in cyberspace, I researched a number of programs. The best one, IMHO, is Safe Eyes. It is installed on our machines and it has been doing a spectacular job. It has received all kinds of accolades and recommendations from many sources. Pay a flat fee per year and install it on three machines. If you think that your teen aged son will not look at porn on the net, wake up and install this software so he can't.
