My solution to being technically challenged is always to throw myself at the mercy of those more knowledgeable than me with self deprecation, like "my knowledge of computers comes from the time we were photographing dinosaurs with our polaroid one step cameras and watching movies on beta max and vcr s. I also do so admire anyone who can work in the USA in today's world. I left the work force at the top of my game in 1998 with my sexual harassment waiver on file, and don't think I could do it now. I wouldn't even get in the door because I'd be saying things like, "You want me to do what? Take a drug test to be a greeter at WalMart? Are you crazy? Greeters would probably be a lot better at their jobs if the WERE stoned! (hope I can say that here, I mean no promotion of the notion.). I couldn't survive the politically correct interaction required on the job. The things we joke about where I teach in Malaysia would get me sacked for sure. My colleagues date and sleep with students all the time. It's not even noticed. Common behaviour. Students offer sex for grades all the time too. Chinese ladies get student visas just to come here to find rich sugar daddies and this has all become normal to me after almost 20 years. And believe me we have lots of laughs at non politically correct stuff all the time. Sexist, racial, ageist, ethnic, religious. Nothing is sacred and most of it is usually self deprecating not arrow slinging. I personally think it's so much more fun than to have to watch what you say all the time. Every time I go back to America, I always worry that I'll say something out of line. There's a catch though. It's illegal to insult islam here. So guess what's the most insulted group? Yep, but mostly 'behind the barn' so to speak.
So to get back to proper topics, I truly appreciate those who have the technical knowledge of how these vapour rigs work and understand the electronic interactions of voltage wattage and ohms. Sometimes I have to look up many of the words in some posts just to get what the op is saying.
