Use a Nick Name . When entering chat rooms, bulletinboards and other public rooms, encourage your child to pick out and use a favornick name distinct from their real name. This is a regular practice on the IRC and permits a nice level of anonymity, allowing users to learn more about each other only when and if they and their parents are ready. Remember that others will be less than honest about their identity as well. Report suspicious activity.
Some conduct is illegal in both the real and the virtual world.
If someone is stalking or harassing your child, keep copies and records of the messages and let the authorities know. You may also wish to notify the systems administrator of both your service and the service from which the message was transmitted. The Internet is a wonderful new opportunity for children.
