I agree, and have stated before, that a book as a reference would serve us well to look for answers. But I still enjoy this forum very much. And yes at times things get off topic and we have friendly (and sometimes not so friendly) banter back and forth. But I believe that is what makes some of this so much fun. We joke back and forth and learn about the machines as well. We discuss our horror stories and our great buys and all sorts of stuff. I hope that never changes!!! :-)
