I know I am an old F and this is my second only post but can I share an observation. A great number of postees use cryptic "cntrtns lk u i ". We are dealing with TECHNICAL matters, mostly, therefore such words as dvi will crop up, u is part of dbu and so on. I know in personal emails we often do not capitalise "I" but in a technical forum it does separate the person from the "thing". No, I am not part of the texting culture but I have 50yrs of engineering jargon that I could use to show off and obfurscate. I cannot touch type and the odd typo will creep in, but can we keep things as clear and error free as possible?
