Allow me to demonstrate a bit of the ocean of ignorance in which I am drowning. There are used in this community many acronyms, initials and terms that are unknown to me. I pretty much get the drift of most based on the context (such as "HAD") but I know not the exect breakdown. Is there a thread that defines these cryptic groupings of characters? Or maybe we can establish a listing herein? Or maybe you vets can just share a hardy belly laugh as I fumble about in the dark like when we used to send the new sailors all over the ship to locate a spool of fallopian tubing.

Thanks,

Brad
