How can I change the email associated with my account?

Nobody can help me? I even sent an email to the authorities but not received a reply yet.

When you are logged in to the site you shold see on the top of the page "Welcome back <your screen name>  LOGOUT Update Account"

Click the Update Account.   On that page there is an Email Management section.  Click the Change Email.  In that, enter your old email.   You will be given a dialog to enter and confirm your new email.  Click submit.   

Don't know how long the process will take, if it is automatic or requires manual intervention

You can also click on "settings" under your account name in the box at the upper right.  There you will see an "E-mail settings" section, with a blue "edit" button next to your e-mail address.

Thanks to you two guys. I have tried this and at the end it says that it was successful but when I look at the edit settings options - email settings - private email, it shows my old email again.

I did mine awhile ago but it didn't work w- Cox and I had a heck of a time switching back to gmail.....  anyhow I think how I did it was after logging in, at top of screen you will see you name. to the right of that Custer Service link. Click that, I think you have to log in again. Try that??  I think. 

Forget it. I've been trying for a couple years now with no luck.
