`=>`Internet sites like MySpace, Bebo and Facebook are a great way for young people to keep in touch with friends, but there are things you should do to stay safe.

`2B`

`=>`On some sites you don't have to use your real name if you don't want to, so invent a name for yourself.

`3C`

`=>`You can write lots of interesting things on your online page, but something you must never do is to put your house address or phone number. 

`4A`

`=>`Remember, too, that you mustn't put your friends personal details on your page, or you could put them in danger. 

`5D`

`=>` So the message is: have fun, but take care.
