You can't. Stardoll is basically a a Dictatorship and doesn't want users to turn chat off because that would give them some control over their experience of the game. Or, you could send your question to them, but good luck getting a real answer because their answer to everything is:
Thanks for your mail.
We are experiencing some difficulties with this item/function. We are aware of the problem and will fix it as soon as possible.
We are sorry for the inconvenience!
Kind regards,

To turn the ultimate safe chat off you need to log into the parent zone and select safe chat mode.
you get enough money to buy mw3 you noob
Safe chat is a part of that site for a reason. If you wish to talk about things that aren't allowed there, then find a better place for it.
Go to Private under the chat box and right click "Private" then click off to turn it off, or do like I do and set it to friends ^So only the people you've added can see you on.
On a Minecraft server, chat is always on. If one of your friends can't chat, then it is a problem on their end.
