Netsmartz

This site is run by the National Center for Missing & Exploited children. It has tools and games for teaching children-teens about how to be safe on the internet. It also has tools to help parents and law enforcement teach the youngsters as well. This seemed like a good place to start from, and being that all kids love to play (adults too), it would seem a good way to begin. Make learning to be safe online fun for the children and teens you care for.
