Thank you lurkers and others. The Italian member does well in English; if only I could do so in Italian (or French, or some other language). Actually, we have an international crew here from U.S., Canada, Europe, Australia, and other places, so the language community is wide. As for the opinion atmosphere, I think we do pretty well,with moderators help, to stick to the subject. My sense is that our cultural/political groundings are all over the map, and that is the beautiful thing. Instead of carping at each other, we have some good meeting of the minds even when we don't agree. So if you can bring yourself to contribute comments and stay mostly with pipes, it's all to the good, in my opinion. Thank you, and more-more-more comments are welcome!
