Just for everyone's convenience, I usually always type out the entire word first, then use its acronym subsequently. It avoids confusion 99.9% of the time, assuming everyone who asks actually reads the post (of which I am guilty).
I'm glad this thread exists - I was hoping for something like this.
However, pedantic sod that I am, I would not call most of these acronyms, because you don't pronounce them as a word. I would call them initialisms.
okay im kdding about that but um...ive sat for an hour or more before wondering why everyone puts imo...and i didnt know hat it meant until just now! sighhh ima dork
