WAV; I'm heartbroken; you mean to say you're not an expert? In any of this? All the dogmatic pronouncements over the years have been from a basis of (at best) a dilettante? What about your qualifications? Surely somebody with four (count 'em!) technical certificates must be an expert? Gosh,I don't know what to believe in any more!
I apologise for calling you an 'Antipodean', I should have known from your broad Mancunian accent that your weren't from Down Under. I mistakenly believed that if it quacks like a duck and walks like a duck, it probably is a duck. Can you walk like a duck, WAV?
