Usually when I receive requests for help with software, they are neutrally phrased.
Sometimes, though, they are incomprehensible, impolite, or both. It's hard to do much
about the incomprehensible questions, except to reply with an e-mail that might be briefly
summarized as eh, wozzat?
; but for the deliberately rude or insulting requests,
I sometimes will suggest some
ways to get more useful support.
