    • Just like being a citizen in your community, being a cyber citizen has responsibilities. Use the internet to share knowledge that makes peoples lives better. Keep safe, use good manners, and respect the law.

      Keep some control over the information you post.

Acceptable Social Networking

  • Make sure your screen name doesn't say too much about you.

  • Be wary if a new friend wants to meet you in person. If you decide to meet them, meet in a public place, during the day, with friends you trust. And tell a responsible adult where you're going.

  • Post only information that you are comfortable with others seeing and knowing.

Fundamentals of the internet

  • Consider not posting your photo. It can be altered or broadcast in ways you may not be happy about.

  • Flirting with strangers online could have serious consequences. Some people lie about who they really are.

Fundamentals of the internet
