Thank you for your warm welcome - it's always good to be introduced to a new community with such tolerance.
I've asked the question on two sites - since I am new to both forums, I have no idea which is the most active, or which has the most knowledgeable userbase.
In any case - anyone reading this thread, presumably, will either wish to know the answer to this question, or have the answer to this question and wish to impart their wisdom. Therefore, the thread adds value. There seems to be a third variety of potential viewer - the person who choses to add no value, but to snipe, instead.
