What happens if I signed up with the wrong email address?

If you accidentally entered the wrong email upon subscribing, the good news is that you can still use that same email to sign in to your account if you happen to have it.
Once you've signed in, hover over your name on the top right corner, click Account Settings, and click Update Profile on the left-hand side. You will then be able to make the appropriate changes to your email.
