Great, the two chaps can help me to wrap my head around the newly  
discovered planet by NASA that not only earth like, but also just 11  
light years away (like live just under our nose)... http://

may be prepare search the alien under the sea?  (avoid competition of  
search alien above the sea, like "expedition unknown" TV show).   -  
dave you might not get them back if both get lost in the darkness ;-).
by the way, where is Doug?  if he showed up with fraction of element,  
I donate both to him to help out his tasks on hand... (must be super   
busy).
