>I don't mind threads going off in all directions, but when someone asks a question…

as a rule, I agree with this. but in this case, the question didn't seem all that weighty in the first instance, having been posed without much context (e.g., from where was legitim gleaned? what prompted the question? what is the significance of the suffix?).

my -in-cheek response with the initialism might have been construed as waffling, but has now been rendered moot and I shall delete that also.

addendum: Coffeebean has shown that my reaction to the question was probably misguided. so it goes.
