I’d like to see a dictionary of acronyms used at LJ. Sometimes after finding a post that seems to have my answer, the use of acronyms makes me unsure of the product or material being referenced. Especially in the finishing posts there could be safety issues for a novice not knowing the right definition.

For a current post, you could just ask, but for those several hundred days old posts the questions aren’t always made.

Pease leave out the humor acronyms. While I enjoy them, it wouldn’t help to go through them when doing a serious search to make sure that a post is understood. Coffee lounge is a great place for them when needing a break.

They don’t all have to be “industry” ones. Just need to be for LJ info useage.

The real dream would be tags or categories besides alphabetical. Some categories could be; finishing, cutting, turning, chemicals…

No idea on what is involved, but one of those “wiki” for the acronyms would work.
