In the PREFERENCES area I recommend you start out by clicking on the GETTING STARTED button, which will prompt you to change your password and enter your email address.
Video tutorials are also available here. I don't recommend you change the style or language, however you can if you choose to. It won't break anything.
As Always, contact support if you have any questions or issues.
