    Please list any other acronyms or abbreviations you know of that I haven't listed. Please include the meaning of it too. I'll try to include a few other definitions of "nicknames" of parts and such that some might not yet know. Some of the trim levels (DX, EX, Si) are only by word of mouth.

    Please PM me with any new additions! <-- Click here to PM me! <--

    Oh, and this isn't for AIM speak like "lol" or "lmfao". Thanks.

    I'd actually prefer this to NOT be in the archives. I think this is a big problem, knowing what acronyms mean, particuarlly to noobs. I'd prefer if it were kept more prominant and if I were still able to edit it (though I am able to edit in certain tech archives). If you could get this stickied I'd be a lot happier. Sure, not all the noobs will see it then either, but maybe they'll be more likely to. ;)

    Wrong.... follow the rules please. This is not a thread to come into and ask what an acronym means. You need to actually put down the meaning to. ;)

    I never said I know everything. It's always good to check your facts before you post them in something like this too. Still, PLEASE include the meaning for the acronym when you ask me to add one.

    About the FMIU, that was a typo from the orginal document on my computer. I had fixed it, but repasted the entire thing when I added some stuff in. :lol: Guess I didn't change it on my file.
