If I recall correctly.

dear god. so many acronyms…
Thank you for the amazingly comprehensive list, Crusoe.
Do note that many (if not most) of the acronyms in Crusoe’s list aren’t used here, so don’t throw one in that you’ve seen there (without an explanation) if you haven’t seen it used here also.
Wow. Thanks, Crusoe!

Do also note that many of those acronyms aren’t used anywhere. As that thread started getting old, people started just making them up on the fly, for silliness’ sake. Then again, though, there’s probably a few that started in that thread which have caught on, though I don’t know which they might be.
