AP Style - A couple that can stand alone, and those tea 'partyers'

Some quick AP style updates ...

No longer any need to spell out "grade-point average." GPA can now stand alone.

IV is also OK without any need to say "intravenous."

And "911 call" is already widely known as the emergency call, but AP now blesses it without any explanation.

And those wild and wacky tea party folks (yes, AP lowercases it unless you are talking about a specific tea party organization) should be referred to as "tea partyers" (unless of course they're wearing lampshades or panties on their heads, eating goldfish and overdoing the Earl Gray - then they are tea partiers).
