These kinds of things always seem to happen at the holidays.
The Digital Medievalist website is down temporarily because of a problem with the virtual machine that the University of Lethbridge donates to us and will unfortunately stay down for a few days until the appropriate support technician returns from the holidays. The mailing list is of course unaffected, but journal articles, wiki, and website are all down probably until the new year sometime. However, some of these are available at a temporary mirror of the DM site I've put up at http://hilda.oucs.ox.ac.uk:8081/ and the news-posting form at that site should work in case anyone has announcements to submit.
I can only apologise for the current problems (not of our making) and hope the goodwill of those at University of Lethbridge will lead to the problem being fixed as soon as they return to work.
My apologies, Dr James Cummings Director, Digital Medievalist
