In the main navigation menu (top right), select "Register" and complete the form. You will be prompted to enter your name, email and password and accept terms & conditions. You will not be charged for registering and creating an account.
Once the form is submitted, you'll receive a verification email (be sure to check your Junk or Spam folders if you don't see it). You'll need to click the button in this email to verify your email address. Once verified, login with the email and password you set during registration.
Be sure to remember the email and password used for registration as this will become your account login ID & PW for the service
