younger preteen like barbie and pollypocket.com
all the shows have a website--zack and cody, lizzie mcguire, etc.
one thing I recommend is to have the computer in a place HIGHLY VISIBLE by you!! That means no internet access in her room, etc.
I want to see what she is looking at. My coworker told me that some of the teen sports sites (skateboarding, etc.) had ads for #$*##* (use your imagination) that popped up when his son was online.
I also might be a "nerd," but I do not let her enter "contests," "vote," or give out email address to anyone other than friends directly thru email. She says I am no fun--too bad.
