In the main navigation menu (top right), select "Create an Account" and complete the form. You will be prompted to enter your name, email, and password, and accept the terms & conditions. You will not be charged to register and create an account.
Once you submit the form, you'll receive a verification email (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, log in 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
