I have changed my email address and need to update my user account with the new address
If you have your user account login details at hand, you need to do the following:
Log in to your account and go to the “User settings” page. Enter your new email address in the appropriate field and press the gray “Update” button a bit further down the page. An email will be sent to both your old and your new address. In the email to the new address there is a link which you need to click before the address change takes place.
