Dear Members and Moderators

Thank you for often rendering me much needed help.  However, despite your combined efforts I remain as ignorant as ever due to my own incompetence.  Anyhow, here is a ´Link´ which I found very useful .... and in order to [only partially] repay your kind help, I am posting it in the hope that some of us may find it of some value.

With sincere thanks.
