Apologies for the hiatus in posting (and responding to comments & e-mails); I've had a couple of extremely important projects on which have taken longer than anticipated. Thanks to everyone who has been in touch; normal (better than normal, in fact) service will be resumed soon. The blog should be improving, expanding (in a way) and looking better in the near future. P.S. While I'm messing round with the site, including tweaking the new theme, some things may not work, or may look ugly. Please bear with me, and come back in a few days' time.
