Hi Rob, I wasn't trying to dissuade you. Or offering conclusions... just pondering on what some of the challenges could be. I certainly feel enriched by the contacts I have made as a result of the WN controversy, and I hope the new forum has that effect, for me and for others. I look forward to seeing what you will come up with. As I said, not a techie, but happy to help out a bit. Cheers, Paola?
