Some avatar websites that kids can use to communicate with other kids are:Habbohotel.comCCmetro (Navigate to it from mycoke.com)gaiaonline.comThese websites are monitored by adults to make sure that nothing that isn't "G" rated will go on.
I would suggest two popular websites for kids aged 5-12 are Moshi Monsters and Club Penguin. Your kid can create a profile on both of them, make new friends and care for their avatar.
I suggest: Meez WeeWorld and my fave, Cartoon Doll Emporium!
