I am sorry for the unplanned break in service during the past four days. There was a sudden fault in the system, which my website host has now managed to identify and fix. I hope that things will return to normal from now on.
One consequence of the break is that I have decided to have a complete reconstruction of the site in the coming months. I have been advised for some time now that the present format is not very easy to use with mobile devices. If you do have any remarks to make about the site which might be useful to me in that redesign process, please do let me have them. Thanks for sticking with me, and best wishes.
