From reading the FAQ, it seems like down-rating an entire thread is against the rules (if the tone of the thread is helpful and on topic).
I'm not sure, but it seems as though this thread has been karma-bombed. I rated everyone back up, but i figured I'd bring it to the attention of the mods.
Thanks for the hard work, guys (and gals?).
