Watch this CEOP authorised video.
CEOP is a government body (affiliated to the Serious Organised Crime Agency – SOCA) it also has an industry partnership involving Visa, O2 and Microsoft among others to help in a number of ways including training as many children as possible to be able to be safe on line.
This is all about making sure children can have fun using the internet, have control of their online personas, and know what to do to report any abuse such as clicking on this logo
e.g. Windows Live Messenger. Facebook
There is a public web site where you can find out more, ThinkUKnow , to which you can also point your children.
The internet should be fun for you and your children, which means that what you do to protect them on line should be the same as what you do off line.
