Yes. 

Sit down and talk with your child about common-sense rules for computer use.  You both should think about:

1. How much time per day is reasonable?
2. What sites are ok to visit?
3. Is it ok to IM and chat?
4. When your kid is using the internet for homework, what are the guidelines?
5. What happens when a rule is broken?
6. What kinds of games are ok to play?
7. What should your kid do if they encounter something that makes them feel uncomfortable?
8. How often should these rules be revisited?
9. Will you install parent-survey software? Will you discuss the results?

You should keep the computer in a public place in the house.

As a mom I like the idea of setting rules with input from my kids about their computer use. For a few months now we have used a timer to limit the amount of time they are allowed to be online. We will be having discussions with our kids about your other suggestions. Some of your ideas are things I’ve heard of, but never thought about in terms of my kids. You’ve given my a lot to think about in terms of safety and security. Thanks for the great idea!
