Umm.... SHL stands for Symbionese Human Liberation.  It's a ... a political group that attempts to free the oppressed peoples of the earth ....  oh hell, that sounds even worse that what it really is.  It stands for Simulation Hockey League.  It's a fake hockey league played out with a video game and a set of online forum topics where I have a player that has been playing for literally years and is still mediocre and I play anyway.  Why?  It's fun? (gulp)
