I'd be curious as to what demographic has both, read Dr. Dartnell's book, as well as navigated the labyrinth of this forum to arrive, well, here?
Dr. Dartnell, a private forum is so 2000. There are other, more easily consumed and therefore promotional, venues than a private forum. But of course, you know that.
Who else is 50's, well read, (male), schooled (semi or full), somewhat recalcitrant and perhaps somewhat curmudgeon?
