Warren,

If you use the search function (top right of the screen), there are 88 references fodder on the site.

Some of these may prove useful?

Best wishes

Sir,
Many thanks for this wonderful news, I have been trying to wade into this treasure trove but have not been successful in finding any thing. I am not very adept at the computer operation so possible some information is there but I have not latched onto it so far, will keep trying.
