Guest Treatment
i are a mechanical enginenerd, yet i always try to make complete non runon sentences properly punctuated it is very difficult for one with my edumacation to do this luckily i do not have to put up with this at work.
(do you have any idea how difficult is was to write that?)
Also, I'll purposely refrain from answering a question posed like the one by the original poster, unless I can get some comic mileage out of it. Your mileage may vary. Though, there are exceptions. If a guest can positively be identified as a very young person (high school or earlier) who is seeking information that may keep him home working on acoustic physics, third and forth order electronic networks, and away from joining the ranks of the obnoxious loudest car crowd, then I'll try and help.
I was always taught by my parents to treat guests like family. Observing how we treat each other (registered members/family), guest should feel right at home.
