The first pre-release batch of orders has now been despatched, and the website appears to be working well. That’s not bad in the hands of a technophobe like me.                                                                                                              Just a quick note: the diagram on page 62 did not reproduce well on the first print, so I have enclosed a loose copy. This will be put right on the next run.                                                                                                                                Hope you’ll enjoy the book. If you feel so moved, please pop some feedback onto the site.
