I am one of those people (surprise surprise) who jumps out of his pram when he sees the incorrect use of the apostrophe. For example on a recent trip to the UK (and this is still festering inside me, I really need to discuss it with one of my shrinks...) I saw a pub menu that stated the plural of "Lunch" as follows:
Sunday Lunche's
and I also saw it written
Sunday Lunch's
But one area I'm really not sure about at all is the use of the apostrophe in Acronyms. For example, a MMORPG is a Massively Multiple Online Role Playing Game. Is the plural of this:

MMORPGs

or

MMORPG's ?



Your thoughts please...
