This is my last post. I am leaving out of frustration, having lost yet another post this morning when I tried to add a link. Simple stuff I've done in many forums for many years are no longer available to me here, and only here. No other forums I use have issues. I conclude this forum is no longer functional. I can't quote. I can't add links. I can't view the forum. Nothing but HTTP 500 errors since the forum upgrade. Issues elevated to no avail. I just retired from industry, ending the commute I've used to assess various things suggested to improve mileage. I have a bunch of last data I'd like to report, but I can't. The forum only takes text, like this post. That is unacceptable. We once had a useful forum here, I'm very sad to see it go. This is a very sad day for me. Frank, who is not having fun. PS this is posted single-spaced... yet another forum issue.
