A good screen name won't reveal much about how old they are, where they live, or their gender.
For privacy purposes, your kids' screen names should not be the same as their email addresses.

Get to know the social networking sites your kids use so you understand their activities.
Online dating services allow users to become "members" by creating a profile and uploading personal information including (but not limited to) age, gender, sexual orientation, location, and appearance.
