Incidentally, Tom, why do you write under a pseudonym? Your employers know that you're doing it, we all know what you look like and where you work, and you're hardly covert in a brightly coloured, fast noisy car / truck! I think you've even published your mobile number on here before. Given that you're so easily identified, why hide your identity? Not that it really matters, just curious. Cheers, keep up the good work, Steve.
