Hey ya'll! If you know anything about forums (or about the Internet in general, for that matter!) it's that abbreviations and acronyms are commonplace and tend to spread like wildfire! However, the meanings behind abbreviations and acronyms are not always as well known, so I'm starting a list here with some of the more commonly-used terms.
If there's an abbreviation or acronym you don't know the meaning to, just let me know, and I'll find out and add it to the list! Likewise, if you think of a commonly-used term and think it belongs here, just comment and I'll add it! I am trying to stick mostly to forum terms or artisan-type terms, so don't expect to see NASA or anything like that on the list.
