OH, Thank you DocJohn for explaining it in such detail, I understand now and will subscribe later today. I "google" things all the time-- this should help to make my searches more fruitful!

And thanks Kimmy for taking the time to also further explain.

Hey thanks _zh, for standing by my side-- sure feels nice when someone is so kind to help one not feel so alone and clueless.("clueless" can be a triggering feeling at times for me )
