Thank you. I have linked you in. There was once a time I made a very good living
out of being an "expert" in electro-magnetic fields" and I do agree with you. I
also see that you have links to http://www.iceagenow.com/ but I do fear that
nobody is listening as those snowstorms start hitting the North-Eastern U.S.A.

I do hope that poor Brian and co keep on laughing.
