You know having grown kids, and not having the internet when they were growing up, I never had to even consider monitoring what they are doing on-line.
To SB and those who have young children/teens, what the heck do you do, short of standing over their shoulder every moment watching them. Kids can be so trusting, and aren't looking for these people, that even good kids can be led into danger on-line, when they may think it's an innocent conversation. I'd be worried sick if I had young ones at home. Let's fact it too, kids seem to know a whole lot more about the internet than most of their parents.
