and the comment ...
was from the author of the book!
I sent him a brief email, just to say that it was a lovely surprise to see the comment.
I got an automated response:
"Hello, due to the thousands of emails GP Taylor gets each week, we cannot promise you an immediate reply.
However you will get a reply from GP Taylor ASAP! We are currently dealing with emails sent in June 2006 - if your request is after that time we may not be back to you for a while."
So we'll see what happens there, but very cool all the same!
