This is proving to be an interesting discussion. Basecamp, I checked out. Pelton's site before my initial post. It was disappointing and not informative on this subject. Mark R, the course you are remembering sounds more to the point. I join Bingley in asking if you could supply more info or a website. I've so far refrained from directly contacting CNN or other comparable media organs, on the theory that they will refrain from useful answers based on Opsec considerations. But, after this thread inquiry runs its course, I might try that line of inquiry.
