A computer crash at the end of last week wiped out my email for the whole of 2007 so far, and when I came to restore the Outlook backup file I found that it was empty. So I learned a lesson there - always check that back-up files actually contain something before relying on them!
If you have emailed me over the last week or so and have not had a reply, please resend your email and accept my apologies for the delay.
