We have had another problem this week with the website; the latest plink in the machinery was caused by an unruly plug-in. (The online kind, not the electrical kind.) But all seems to be well now.
The book is flying towards publication (about three weeks left!). I have been doing some last-minute tidying up (the appendix had somehow morphed itself into a giant font size behind my back), and we now look pretty good to go.
