Greg, I must disagree with you completely... No one is "attacking" you
personally. John is NOT out of line. He seems to be up to date on the
facts regarding the pairings of the stones. Nothing he said that I can
see is incorrect, however your attack on him seems rather "harsh". I
feel your comment is irresponsible, scientifically and personally.

Your comment: "...With over 10kg of this material in pairings known so
far, I am willing to bet there is likely a good amount more still. I bet
the Brachinties are coming out of the woodwork to be tested...."

Possible, but the SCIENCE is more important than conjecture and feelings.

Regards,
Eric
