When you use the WordPress Lost-Password Function you will see a popup window similar to this:
This is core WordPress. In short, that means it is not easy to edit and usually best for novices like ourselves to leave it be.
Our site uses UserNames and not email addresses to log in. This message suggest you can recover your password using your email address. You can not. You must use your UserName. If you forgot your UserName then use the Website Help Request Form (under the help menu) to request our help. We will lookup your UserName. We cannot change it and we cannot see your password.
