I work in this area, and I would not let my child do it. I would not let my child have their own computer in their room, the Internet is a great place and a SCAREY place. When they turn 18/21 and on their own, off to college, etc then they can decide, at my house, I monitor the Internet usage of children.

Not because I don't trust them, but I have seen the other people on the Internet, them I don't trust!
