I will now be completely unavailable for the next few weeks, due to having to make two foreign trips. Unfortunately this means that this month's site update had to be cancelled :-( I will have some new content along with a new version of the site ready for the end of next month. If you still wish to e-mail me, please remember that there will be a 2-3 week delay in receiving a response, sorry!
