There is a lot of good/interesting information on this thread. I appreciate all of your participation. Let's work together to get this information out and if we have differing opinions, great.

Let's not challenge credentials. Let's remember that it's people with credentials that got most of us here (sick and mercury toxic) in the first place.

Most people who are sharing information on this system are:

(1) People who have credentials, or
(2) People who have first hand experience.

Both are valuable.

A caring person with credentials can be a powerful force. A caring home researcher can be a powerful force as well. An uncaring person of either kind can be destructive.

If we want to challenge information that someone posted, let's post information. If we make our posts in a way that shows quality-of-character, the information will be more credible in the eyes of the reader.

Kindness gives leverage to our message. Let's make sure our message has impact.

Thanks again for all of your contributions. They are valuable and I know first-hand how many people will read them and benefit from them.
