Thanks v.laurie... some really helpful explanations for an old dinosaur like me.

Great articles that give me a concise way to inform my Teen about the Internet and its responsible use. I Thank You but he won't: I intend to give him a pop-quiz on Wednesday. :)

As a retired MIS director, I enjoyed reading these explanations. Something about an old dog and new tricks. Every bit of information was good and accurate as I remember it. Thanks for such an interesting article. Now I don't have to explain things to family members anymore. Nahhhh. Who am I kidding?
