Hi jvr3419
Thank you for your post.
I am so glad that I did not dismiss your post as just another ordinary sharing.
I have found some very valuable information in your post
They have answer a question I had for many years.
Your post gave me a direction.
I read up on them and learn so much on an area I know so little.
I really appreciate your generosity and kindness to care and share your personal experience in here.
In the meanwhile, I need more time to organize what I have learn before I can post them later.
