The internet can provide hours of fun especially if the weather isn't so good, but think about what you use it for.
Never agree to meet someone you've been speaking to online that you don't know. They may not be who they seem. Anyone can pretend to be anyone online and they might not always be telling the truth. If you really must meet up with someone, tell your parent or guardian and ask them to go with you.
Facebook, Bebo and Twitter are a great way to keep in touch with your mates but think about the information you share on them. Never give personal information like your address or phone number. Don't accept friend requests from people you don't know either. It's so easy to post online from your computer or mobile phone that we do it without thinking and sometimes regret it. It's worth remembering that once you have posted something, anyone can save it and re-post it.
Sadly some people try to persuade young people to post inappropriate messages of photographs. If you ever feel uncomfortable about something someone asks you to do in a chat room or on a social media site, make sure you tell someone.
If a website makes you feel uncomfortable leave it straight away and tell an adult about it as soon as you can. Let them know if you receive a message that frightens of scares you too. Think carefully about your password and avoid picking something obvious that someone might guess. Use a random mix of letters and numbers instead and try and change your password regularly.
Use a strong privacy setting when setting up your profile on social networking sites. That way only friends will be able to view information about you.
