You can change the main email on your account should you need to. Simply login to the parent dashboard here, then expand the Settings menu item on the left hand side by clicking it. You will see a link called "Change email", click on this. (see below)
On this page you will see two fields, one which displays your current account email (which is disabled) and another field for you to enter in your new email.
Once you enter your new email, we will send a confirmation request to this new email and another message to your current email to confirm it was you who made this request.
Simply click on the link from the new email and the email change will be complete.
