Chatrooms and IM
There are lots of sites around that allow you to talk to other people on the web. Chat rooms give you the chance to have a conversation with other people and get instant replies. Online message boards and forums let you post questions or comments and ask other users to give their opinion in their own time.
It can be a great way to chat to other people who share your interests, but you should always be careful not to pass on any of your personal details.
You should always keep in mind that internet users can pretend to be anyone they like. They can lie about their age, their interests and whether they're male or female. No matter how long you've been chatting, remember that they're still strangers; you don't really know them at all.
