I'm not sure where to post this question, but can anyone see where to change your email address on the ZA site, which I believe is:

I log in and see my info "Logged in as...."
Clicking on that logged in link leads me to "Manage Account".
Under My Account, I can "Change Information", "Change Password" and some others as well. But nowhere do I see a way to change the email address.
The "Live Chat" link at ZA "Support" worked, and the support person changed my email address, but she said that I should be able to do it myself.
I changed email addresses at 8 different sites, but I must be blind at the ZA site because I don't see it.
