i went with Fantage! I love their safety options and chat-filtering system! I have them on no chat for now so that i can monitor them... but they like to play games like fashion show, staries, and rocket board! they like the secret agent missions too!
I love www.funology.com. It has activities for kids including crafts, games, recipes, science experiments, jokes, magic tricks, and odd facts. It is a good way to find things to do when my kids are bored.
My second favorite site is www.nickjr.com. My preschooler likes their shows and web site. (With my help)
Neither of these 2 sites has chat rooms to worry about.
Those are all great websites. There is also a kid safe girlie website coming out this spring for tween girls called iBesties.com. It is best friend quizzes and scrapbooks for girls ages 8-11. It follows all the COPPA laws and the no boys allowed laws!
