You may have noticed already that some of the web pages have changed in appearance. I’m in the process of updating the site, so at the moment there is a mixture of old and revised pages.
The most noticable difference is moving to a slightly wider page view, which will hopefully make them easier to read. Nearly everyone is now using larger, higher resolution screens than when the website was first written. It makes sense to take advantage of that. There are a number of other changes that are not really visible, but improve load speed and efficency.
