Jon, perhaps you're right. I guess seeing so much knowledge splashed around here, I got to thinkin' that this place could answer just about any question put to it and present every point of view on the subject. There've been only a few questions that I've ever desired help with. Not many were worthy thread material. I guess my interests were too specific and maybe I should have searched elsewhere before taxing the threads here. My inexperience with the web, other forums, search engines and sites etc. probably contributed to my misguided attempts.
