How do I change my email address? (New UI)
If you need to change your email address, click your profile icon in the upper right-hand corner, then select "Email Address" (or click here):
Then, type in your new email address in the "New Email Address" text box, and click "Change Email Address."
Shortly after that, a confirmation email will be sent to the new email address. Click on the link in the email to complete the email address change.
