I am aware that it is not feasible to cite a source for ever statement of opinion; however, I believe at least some general attempt of sourcing information should be made. The use of reliable basis for one's opinion might keep the personal, snippy, replies that sometime occur at a minimum.
This no attempt on my part to regulate information that occurs between nor by any individual poster, for Jim establishes his rules since he owns the Board, but it seems we all will learn more if we are respectful of other viewpoints and attempt to support them by using specific statements.
