You will see two options; ‘Login’ and ‘Register’.
Click on ‘Register’. It'll take you to an online form where you can fill in your details to create an account.
After creating the account, you will receive a confirmation code in your email. Key in the code in the text box provided and click ‘Confirm’.
Once you input your confirmation code, you'll be taken back to the login page to login.
If you accidentally close the login page before entering your code, you can resend the confirmation code again from the login page.
You can now login with your username and password and start connecting your controllers - using PC or Mac or IntelliLink. You can check out the connecting guide here for PC or Mac or IntelliLink.
