October 20th 2001 : Geocities, the host of this website, have decided that as it is (and I quote) "very popular" they will turn it off periodically and have invited me to "upgrade" (i.e. pay for web space!) I have therefore done so - but NOT with Geocities as I have no intention of submitting to what is simply thinly-disguised blackmail. The latest edition of this site is at http://www.eyga.org.uk - please click here to visit the site at its new address. In future, this Geocities site will be no longer updated although it will continue in its present version for as long as Geocities permit it to do so.
