Just to let you know that there are now more than 30 postings on this subject. I'm getting a sense that it is becoming more like a soap opera than a television drama serial. A drama serial has a beginning a middle and an end. A soap opera just keeps going on and on ... and on ... and on.

I have ignored previous calls to stop posting on as I think we have now entered a new stage - where people ramble on forever about things which are increasingly irrelevant to the original subject (just like a soap opera).

We now must surely hold the record of the largest number of postings on this site, so feel free to carry on and on ... and on ... and on ...
