Perhaps the adage "better to be silent and thought a fool, than to speak and remove all doubt" applies here. I have been a member for many years and always found the information shared openly in the spirit of craftsmanship and brotherhood. During that time I have seen foolish things said and incorrect statements made. Usually the source was not proud, and everyone was glad to raise the bar. However on occasion there is an outlier, and perhaps Ed1 is such a person.
