I've read and posted on some of the other areas of the forums already, but before I go too far, I'd better ask for help...

What do these stand for:

WILD (something, something Lucid Dream)
MILD (same as above)
RC (Cola? Just kidding!)

I know there are so many others. Can someone post the different meanings of these acronyms? Or is there a spot where they are explained? Thanks!
