Yay for punctuation
"But what about "P.C." with the dots? Does the dot remove the need for the apostrophe? ie. "P.C.s"? Shouldn't "PC" be "P.C." anyway, meaning that "PCs" or "PC's" are just wrong?"
Yep, should be P.C., H.I.V., A.T.M., A.T. & T. etc.
Hey look! ., , I'm sure that's not right. And I just used an apostrophe to replace the letter i. Then I started a sentence with "and" so now the gods of grammar are going to kill me.
I saw a great one yesterday though, it was a guy that used "etc" instead of "e.g." then the old "to" instead of "too".
As for apostrophe vs single quote, an apostrophe goes in the middle of a word like "don't" single quotes go round a phrase 'something like this'. </2 cents> <coat>leaving</coat>
