Thanks for all the info, Peter, much appreciated as always.

Just curious - Were you a PHD plumber/builder or professor of some kind before? Your knowledge of the above tells me you must be quite IQ.

My husband is.

Great posts Peter. Karma your way.

Uh? Are BEV and Peter wife and husband? Or I am missing something in interpretation of your message BEV?

No. Poor Peter if it was so my husband would say.

Sorry for the confusion.

No - I've just been around a long time and done more than enough! But I did fix computers for a living in a former life, but that was when they used punched cards !

Best qualifications ever, Peter - Self-Taught and Gained Experience through others. I am sure you would put a lot of new students and graduates to shame these days.

Thanks again.
