You have no idea what a lovely Christmas gift you gave a number of us in your last question, lt. DM, Schmaffy and a few others, including me, go crazy (in a good way) debating the finer points of grammar and punctuation. I don't recall having a dust up about capitalization before though. As it's such a busy time of year the others may not chime in unless they are goofing around here and avoiding their responsibilities like I am.
Anyway, I capitalize Nutter. First, doing so accords the term mock self-importance, setting it on the same level as a nationality. But more importantly, it distinguishes the SC.net folks from the run of the mill nutter. In British slang, a nutter is a crazy person. A Nutter is a crazy person with an excuse and the backing of a bunch of other crazy people.
But then you have smax and visions and the like. These people apparently have no shift key on their computer key boards. so to them we are all nutters. they seem to also lack commas...but they're good at periods (sorry...full stops) they like to use them in ellipses...a lot. don't get me wrong...i love the way they write...it's like their own accent coming across in print.
