I'm fairly new to this stuff (a couple of years), and I've been pretty focused on just doing what I was told (thanks Paul , so I haven't spent a whole lot of time on the forums. Now that my process works pretty well (and consistently), I need to 'refine' it. So, I'm reading posts on methanol recover, and dry wash, etc.
One thing that I run into is abbreviations I don't know.
I was wondering if it would be possible to build a page of standard forum abbreviations? I was thinking of a single page and not a discussion (with many posts). If necessary, there could be sections specific to each forum (quality, equipment, esterification, methanol recovery).
If this is considered a good idea, then perhaps a sticky in the appropriate forums to the page.
Or has this already been done and I've missed it? :O

It probably should be a sticky (if it isn't already).
I'm still guessing on some. Some things have multiple abbreviations. Likewise, there are a few abbreviations that could be ambiguous, but are usually clear from the context.
AE - Acid Esterification
AGW - Anthropogenic Global Warming
Alkaline - Basic solution (pH > 7). Usually having a base such as NaOH or KOH added.
ATF - Automatic Transmission Fluid

B20 - 20% Biodiesel, 80% Diesel
B99 - 99 (or 99.9%) Biodiesel, 1% Diesel (some tax regulations require slight amounts of Diesel, and thus this is a commonly available commercial mix).
B100 - 100% Biodiesel
BD, Bio - Biodiesel
CAT - Catalytic Converter
CAT - Caterpillar (heavy equipment manufacturer).
Caustic - Generally considered to be either Lye (Sodium Hydroxide, NaOH), or Caustic Potash (Potassium Hydroxide, KOH).

WVO - Waste Vegetable Oil
Yellow Grease - Another term for waste vegetable oils
Thanks Jon for some additional suggestions. Also, see the expanded "Glossary" in the archives:
I can't believe I missed Acid Esterification and FPHE (updated above).
I had asked about stickies, but perhaps you're right that it just should be moved (or reposted) to the correct forum.
Perhaps I'll consider expanding the glossary that is in the archives.

Hey this is great! I followed the link to the glossary section and the archive.
But I was wondering if it would be worth making it easily available everywhere. Either a sticky in the forums, or a 'Glossary' link on the page. Of course, the downside is that everything becomes a sticky or link.
