Using the internet has become a really fun way of keeping in touch with friends and family.
There are loads of ways of doing this, including IM, chat rooms and through gaming and blogs.
Some people have met their best friends by chatting online and some people have even got married after meeting in online chat rooms! But there are also some nasty people who use the internet to meet people, so you need to make sure that you keep yourself safe while still having fun.
Some chat rooms / forums are moderated and this means that an adult is watching what is being said to make sure no one is being nasty.
They can delete messages and also ban people from leaving messages if they are upsetting
