I think you are correct regarding your own email address, which you apparently did not register with WP in your own profile's preferences. However, my email address is registered with WP, and therefore, when you are editing THIS page (my talk page) or at the top of the page, to the left, you should see the option/link: "E-mail this user." If you click on this option you should be able to send a message to my email address, to which I would respond if you . However, it may also be that you cannot see the option I am referring to because you have not registered your own email address. If this is the case (I am not familiar with this scenario; it is news to me), then I suggest we just forego the whole exercise, as it is becoming too involved. Be well and success in your own endeavors,
