I have managed to do something stupid to the office computer, which I am pretty sure that I can fix, but which is going to take most of the rest of the day. In the meantime, although I can do limited bloggo posts, I can't do any emails, so it looks unlikely that there will be a post to Usenet today. Dale, if you manage to read this, can you post the details to as many groups as you can? Thanks, mate.
