Thank you very much for your invaluable post. I am going into a meeting with parents and our school’s principal today and this will be the topic. You have given me additional resources. Take a look at the post I wrote last night, about what parents can “scan” their children’s and friend’s social networking pages for safety leaks.

Any more insights from you on this topic, would be very much appreciated.
