Great to have ST back participating on the board. In my opinion, one of the most knowledgable, if not the most knowledgable, posters on this board when it comes to understanding the technology and being able to explain it in relatively lay persons terms. ST is definitely one of the go to reads on this board. There are others obviously, FJ et al, who really understand the POET process and its potential. I just wanted to take a minute to thank all of those who contribute and take the time to educate those of us here who, while invested, don't really comprehend it. LZF
