When I either an acronym or an abbreviation and I make it plural or past tense, I tend to use an apostrophe between the main word and the suffix, like this:


discontinue --> D/C
discontinued --> D/C'd

Volkswagen --> VW
Volkswagens --> VW's

sport utility vehicle --> SUV
sport utility vehicles --> SUV's
sport utility vehicle drivers --> morons (DOH!)

Does anyone else do this?
