Is there a way to change my login/login email? I could change my email address on the profile description page, but apparently that doesn't change my login email. I see that there's an option on my profile menu bar to add a different login, but apparently when I clicked on the option it doesn't work it only makes me relogin with my old email.
This answer over on meta.SO should help you. In summary:
Use the My Logins link on your profile - you can add your new email and remove your old one.
I am able to change my login e-mail now. This is done through adding a Google account, and here is the instructions from meta.SO.
