Older teens may want a public profile to promote a band or other creative work. In this case, have your child create a second, public profile for the project while still restricting the personal profile to family and close friends. It's best to set up these profiles with a free e-mail from Yahoo or Google using an alias that can't be traced back to find personal information.Encourage your kids to tell you if they're victims of cyber bullying or harassment. Many teens will try to deal with this on their own, which can have disastrous consequences. If your child knows who's behind the harassment, involve the other child's parents or school officials. If it's anonymous, remind your child that it's not personal; some people just think it's fun to say mean things about others.
