One of the most confusing things I've found about the LFS community is the amount of acronyms used. Is there a FAQ anywhere that explains them or could some of the regulars divulge some of this arcane knowledge? 
For example, 'WR'. I know it has something to do with a very fast lap, but I have no idea what it actually means.
