Following up from my last post, I wanted to share some information on safer internet use for children, very kindly provided by Sarah from the Internet Watch Foundation:
A PDF guide on using software to stay safe on the internet: Using Software to Stay Safe on the Internet.
Some links which may help you choose a filtering product and find out more about online safety:
Plus, for more information about the Internet Watch Foundation (IWF): http://www.iwf.org.uk/public/page.103.htm
I recommend that all parents look into this who have kids that use the internet.
