I liked the above thread title so I used it.  Monk, I totally agree with you, I did find this article quite interesting.  It seems to be very related to POET's work.  Morning Star, thanks for your article this morning.  I learned about Chalcongens  today  (My spell check thinks I spelled Halogen wrong) Very interesting as well, thank you.  Not a lot of posts today but the content was neat.  SHV, perhaps your theory has merit.  I have no idea but interesting.  If I might borrow a phrase from our Cheapinski, ECWB (Eternal Cosmic Wisdom Bro).  Kind of catchy for a "left coast" guy.  (don't worry, still very well grounded here)   Cheers  BT
