Wart, just to make sure you know, I didn't write the text in #21, I gave full credit to a poster called 'ed' who commented on another website regarding this article. Valin posted the link to that thread, right under this thread's title.
Sorry, it's just that internet thieves, claiming others words as theirs are comtemptible. Darn, I wish I could write like 'ed'.:)
Thanks for this thread and for posting "ed"s comments.
Wonderfully lucid thinking!
