Thanks, Jeff.

I'd glanced around the site but missed that page.

It's an interesting explanation, and sounds reasonably logical (and like you said, the elements that one would guess would be breaking them down are probably mostly eliminated.

Seems to me, however, that if this gentleman is trying to convert others to his methods, he might conceivably get farther in that direction if he didn't start off his explanation by labelling anyone asking about this issue as "irresponsible". Was I seriously considering his technique, that would have been quite a turn-off to me. :wink:

Sara :D
