One particular website is www.cartoondollemporium.com. This website lets young girls build their own avatars, create their own rooms, make friends and so much more. This is like a social network for young girls, but instead of providing personal information to other members, you will only be able to show them the dolls you have created and the rooms you have made. This is particularly popular amongst young girls of this age, but may extend to people outside of the 11 to 13 boundaries.
Stardoll is another website that lets you chat with friends, or chat with completely new people. Just like the Cartoon Doll Emporium, you will be able to dress up your dolls and apply makeup precisely how you like. You can even use celebrity dolls, and give a makeover to your favourite celebrity.
IMVU is popular, too, an incredible social network that uses 3D graphics to ensure that the experience is as enjoyable as possible. You can chat just like you can on facebook, and you will have a contacts list with a list of people who are currently online. You will be able to go to your friends’ rooms and meet your friends’ avatars, or invite your friends to come to your own personalised room and have a chat.
