E-mail address: viewfinder --at-- ferranti.sol.co.uk (I hate web crawling spammers so you will need to replace " --at-- " with the familiar symbol).
This address was changed on 14 April 2008; unfortunately this was necessary because of a rash of spam, possibly related to the theft of e-mail addresses from my web host a few months ago. I apologise for any inconvenience.While I aim to respond to all good faith e-mails, and respond to most e-mails promptly, prompt responses, are, for various reasons, not always possible, and occasionally e-mails get put aside and may be lost, or may fail to arrive. If you e-mail me, expecting a response, and do not receive one, do not hesitate to remind me. I prefer the e-mail to the telephone, but if necessary, I can usually be contacted on (+44) 1 337 841142 or via (+44) 1 337 840551.
