Right, thank you, all becoming much, much clearer to me now. More most welcome; please keep 'em coming. Publication may not be for a month or two, and I can let you know when. However, if anyone wants me to send them a copy of the article when it's written just pm me your email address. I don't think it'll tell you much you don't already know though; many of you have much more experience than I do! My 'expertise' as a writer consists in knowing a little, picking brains of those who know more, and sounding like an expert when I'm not!
