The reason why you should keep your personal information safe from people you don't trust online is that you can't be sure where it will end up, what it will be used for and who may contact you.

There are times when you have to give your personal information online - for example in registering for new products or to friends who you can trust. The important thing is to remember that this information can then be passed on to other people or organisations.

Often companies will ask you to register with them online because they are interested in selling you something. Don't be fooled by some of the online quizzes or raffles! It's best not to give out too much personal information on forms or quizzes - especially those which ask for personal details of your friends or of other members of your family. Always ask for an adult's opinion if you are unsure.

Be careful when filling out your profile online. These are public areas of the internet which people can search on and then contact you.

Always choose to keep your blog or profile private if possible. This means it can only be viewed by people who you allow to communicate with you online.

When entering a chat area you are often asked to give out your Age, Sex, & Location (ASL). Stick to your nickname and don't be too specific about your location.
