Knight's Tour Notes website gone

I've just noticed that my old Knight's Tour Notes website has vanished into the ether. This is not unexpected, since it was housed on a dial-up site which I have been unable to access for several years. I will now have to relaunch it on my Mayhematics site, or start up a new URL. This may take some time. I will probably want to put it into a revised format and improve some of the diagrams.
