Shirley, Bob and all ... Well, yes, I guess I was a little testy about things yesterday, and yes, I probably overreacted, and yes, I worried about it all night and all through church, and yes, I probably need to get a life. So, I, too, apologize, but don't you think that every once in a while it's good to discuss methodology and documentation. Some of us may not be comfortable with research, some may be just beginning our quest and some may be struggling to remember the research techniques we learned in high school, college or graduate school.
