      - Post Script: describes several improvements I would like to have
        made, but which didn't survive the CUT in my publishing plans. I
        don't feel guilty about them. Wistful,...?.. maybe.

      - Commercialism! As publisher, I see the need to advertise and am doing
        so on a limited basis....primarily via "jetwords.com" website and
        word of mouth. The order form at the end of this book is also a
        reminder that is already a little out of date. It does reference
        the website. I welcome feedback and suggestions on all topics. My
        current e-mail address is posted in this website.
