We all have lots of questions as you do John, but please bear in mind that we can't demand answers from Michael
(please read the Code of Conduct!), all we can do is ask our questions politely and
that he chooses to answer them! Where one of us has an answer that we're sure is correct we'll happily share it..but on this one..it is a discussion point that i see you've been enjoying with us in the other threads!
