I asked a legitimate question, bringing the topic back to the top, opening it therefore to new comments.

I did not expect unhelpful comments such as "haven't you heard of Google........." and  "read the old comments".

It was mean and unnecessary.  I am new to this forum, but not to others.  I know that some stalwarts can be intolerant of newcomers.  I am new, but I won't be talked down to, not by anyone.  
Not to worry, I have answered my own question, and I do hope that it can help others in the future.

Good luck with your forum - I will be a silent reader, not contributor, from now on.
