Bob mentioned the members that never come back after a long session of troubleshooting help. That is a pet peeve of mine.
I have worked on machine tools that I'm not familiar with and have contacted the factory service department for some guidance. Sometimes it takes several calls. After fixing the machine I always make one last call to let them know what I found to be the problem. It helps them and I like to thank them. I often filled in on the service tech line when I worked at Bridgeport Machine Tools. Nothing like being appreciated for all the tech advise. Most customers never called back.

Yes that is truly annoying. But around here plenty of folks give back too and that makes the chattel tolerable. Not that I'm able to offer much advice, but those of us who can't teach, donate.
