This idea has been floating around in my head for a while so I wanted to see if people thought it was useful and can add to it:
I want to compile a list of acronyms commonly used in automotive forums. It's mainly for newbies, but I recall a time when I needed to define a lot of acronyms when visiting forums due to unfamiliar acronyms (to me) that were commonly used.
My plan is to start and have others add as replies. I will then edit the original after a while to include everyone's suggestions. I'll make it a sticky for easy reference.
