If you tried to register and where told you had to be 18 or over, I'm afraid you where told wrong. o0o00opsss! Palace Planet is an all ages website, the restriction was a script error that has been fixed.
We do ask you for your birthday when you register, but this is just so you can be added to our birthday calendar. In the user CP (control Panel) you can choose who is allowed to see your bithday.
