Most young people now have social networking profiles on sites like Facebook or Twitter. Althought they're great for keeping in touch with friends and family, be aware that not all those who access these sites have good intentions so you must make sure you only accept friend invitations from people you know and trust. When on social networking sites consider your privacy settings carefully - it is wise to allow only your friends to see your photos, statuses and any other information you’ve uploaded.
It’s also useful to remember that once you post a status or upload a photo it is in the public domain and people can send it on to whoever they like. Once it's out there, you cannot get it back. Think about whether you would want pictures or information shared with your parents, teachers, future employers or complete strangers? If the answer is no, then don't upload it.
Chat Sites, Audio & Video and Instant Messaging
Websites and progams that allow direct and immediate contact between remote users via text, audio or video introduce other problems. In some cases it may not be possible to verify someone's identity. If you're not sure that a person is who they say they are proceed with caution.
If you want to know more about staying safe online please look the Thinkuknow website. It’s run by CEOP, the Child Exploitation and Online Protection centre and is very helpful to young people and adults alike.
