Welcome to the new version of our web site. With the old version, I found it difficult and time consuming to change things and add new material. So, I decided to change the way this all works so that there is some introductory material (at the top) followed by a series of articles that I can add to and update using the Blogger system. Hopefully this will allow me to add material in little chunks and this will make it easier to make the site more dynamic and (again, hopefully) interesting.
