How do you manage your children's computer use in your house?

It's all too easy for anyone to accidentally click on something and end up with hardcore porn on their computer screen. But you can't keep your children away from the machines, either.

We make sure someone's always around when they're playing games or doing other stuff on the computer and make sure we know what they're doing.  It's a little easier now at ages 5 and 3, I think, but that's the model for the future, too. No computers in bedrooms.
