There will be no new posts on this website for a few days because the site is being moved to a new server. I would not be able to have this website without the help of Paul Melnikow who set it up and showed me how to post, and has been there when I needed help. And Lisa Goodlin who has also been there these last 4 years and is now taking over as my main technical advisor. I am very grateful to both of them and all the other friends who help me with my technical difficulties.
