I wish to apologise to anyone who may have tried to contact me
during the past three days - our local file server decided it had
had enough and crashed its disk. This caused major problems here
at the University, as you can imagine! All is well now and if
you think your message may not have reached me, please post it
again.
Thank you.
Best regards
Rogan Roth.
