Thanks for all of the input & thoughts.

I was looking for more technical information - not because I don't think that the education piece is the most important, but it's only one part and I would like to tackle it from various directions. I've seen IT professionals at work click on screen savers from e-mail. Everyone does something dumb now & then so while I agree education is the first line of defense - like I said, they are only 12.

I'm going to spend some more time investigating - and I have some good threads to follow from the input here. Thanks again.
