I need to apologise because we've had to disable anonymous comments on my blog due to the fact that for some reason
this post in particular seems to be attracting an inordinate amount of spam advertising various "exotic" items, websites and services. Guess it must be my kinky porn star name... either that or the word "prong" gets those nettlesome spam-bots all excited.
Anyway, in the exceptionally unlikely event that you did want to comment you can still do so but you'll need to be a registered Simple Talk user.
