How do I change/edit the email attached to my account?

To change the email attached to your MV account, go to your drop-down menu > My MV > Settings. From there, locate the section named "Account" and click "View".  Then, locate the section named "Email", here, you will be able to enter a new email address (make sure that it isn't one already in use on MV). To save your changes, enter your current password and hit <Save>.
