title: iTunes connect will not let me add myself as a user
body: <p>I am working on an app in iTunes connect for a client, under their iTunes connect account. I want to add myself as a user so that I can get email notifications of updates in app status. When I try to add myself as a user I get the following message:</p>
  
  <blockquote>
    <p>The email address you entered already belongs to an iTunes Connect account. To continue, enter a different email address</p>
  </blockquote>
  
  <p>I am using this email address on my own company's iTunes connect account, but not on my client's account. How can I add myself as a user?</p>
