Update... I figured I'd pick up the car and drive it around locally to
gather more experience. A friend dropped me off at the shop and I drove
off. I got about 2 miles away when Cheech & Tommy started doing their thing
(smoking heavily). I turned around and dropped it back at the shop.
When I got back to my office, the was a bounce message from the 200q20v
list. Hmm, what the heck? I subbed an alternate addressed and forwarded
the message below to the list. Then my original post seemed to get through
(4 hours later). One of those days, I guess.
