It's a whole new stinking class! After spending almost ten years working on my book on exchange rates, it's dang near done (and will be published by Routledge). As a consequence, I've done a major revision of the class. I completely threw out about 1/2 to 2/3rds of the old version. It's now jam packed with fascinating and, I hope, relevant information. Oh boy! (April 11, 2008)
