I would like to hear your comments and any correction or addition you may have, so please send e-mail to:
(Please cut and paste this address if you want to send mail. I did not use a clickable link, because I want to avoid unwanted commercial e-mail)
Due to the fact that life is very busy, I am unable to answer my e-mails immediately. Sometimes this has to wait until my next holiday, which may take up to a few months. I apologise for the delays, but please be assured that I will reply to all your serious messages eventually.
