If you want to change the email address associated with your account, and thereby also the email address you log in with, you first need to log in to your account.
From the main menu, click on "Settings"
In the "Personal Information" tab, click on the "Change email address" button
Enter your new email address twice and click "Save personal data" at the bottom right of the page
You will now receive an email to the new address you entered containing a link to confirm the new email address. The link is valid for 20 minutes, and if you do not use it within this time, the email address will revert to the old one, and you will need to repeat the steps above.
Once the new email address has been confirmed, we recommend that you go to "Settings" and click on the "Log-in method" tab to double-check that the new email address is now registered there.
Please note that you are responsible for updating the information on your account. If you no longer have access to the registered email address, where your login details are sent when you request such information, the only option is to register a new account and start over from the beginning.
