I have moved this site to a WordPress format, which will allow a number of improvements.  You can like things, follow things and comment  on things.

This new site is basically a blog, which means that new things appear here.  But there also pages of more permanent material, much of which I have imported from my previous practice site.  There is a search facility, which should find anything on the site, whether added as a blog or on one of the permanent pages.
