"Mafac" (or, if you prefer, MAFAC) is a name derived from the initial letters of the name of a French manufacturing conglomerate. (I have to admit that I don't know what the non-abbreviated name was, or care enough to look it up). So does one capitalize it or not?
I don't, using the example of words like "scuba," ("Self-Contained Underwater Breathing Apparatus,") "laser" (Light Amplification by Stimulation of Emitted Radiation), or radar (RAdar Detection And Ranging). Those are never capitalized in ordinary usage.
On the other hand, you have words like NATO (North Atlantic Treaty Organization) or FAQ ("frequently asked questions,"), which almost always ARE capitalized. Read the Wikipedia article on "acronyms and initialisms" if you really want to delve into this.
The bottom line seems to be that either Mafac of MAFAC is defensible. I like lower-case because I'm lazy and it saves me having to hit the shift key, and also because MAFAC looks kind of angry in all caps like that.
What do you guys think? Should we choose one or the other and stick with it? I mean, don't we need some organization and discipline around here? Maybe someone should set up one of those online surveys.
I should have been working fifteen minutes ago, but this is really important.
