This is GameGuidesOnline's guide to making gold in PDF format. It's not a horrible guide, but not the best, either. It looks fancy, and they use Blizzard's images, and in doing so, it violates fair use laws. I guess that makes their copyright null and void? I know that two wrongs don't make a right, but what the hey. Here's the guide, hosted on RapidShare. Enjoy!
