just finished reading all the comments in this thread.
We are all here to share, learn, and contribute. Some of us are all too familiar, experienced and very well versed in what we do. Some of us are not and are on a journey to learn and expand on our knowledge.
"Share your knowledge. It’s a way to immortality".(Dalai Lama)
We all have the right to comment and add our opinions. Common sense, respect and courtesy should always be remembered though.

happy new year to all.
