Thank you for the numerous explanations that you have provided as YodaSolo at GEA. You are probably more responsible than anyone for my becoming a TGMer, albeit a novice one at this point. The fact that you always explained things there in a manner that was understandable for this newbie, and countless others, makes you a helluva teacher.
Ed, thanks for pointing me to the appropriate post. I have been away, so I came to this thread from page 3 as I tried to catch up with the most recent posts.
