Dear Brian 'Chick' ?? Just like to point out to you that not all members of this correspondence group are blokes, Brian. In my professional life I would not refer to you by such a name and would prefer if you did not do it to us women. No offence meant of course. I am enjoying the debate so let's be inclusive and respectful of all participants.
