I haven't clicked the link, but it was indeed given out a while ago (that's how I got it).
As for the class itself, it's not very interesting... a full BAB sneak attack class that gets a few interesting abilities (Con X 5 to run speed and Int to initiative) along with lots of interesting weapon proficiencies... not much else. It's a decent one level dip since you get a bunch of proficiencies, 1d6 sneak attack, and full BAB, but serves little other use.
