I'm not trying to rain on anyone's parade here, but felt this was worth pointing out. "Who Moved My Cheese?" is an actual book in print. As in, for sale. You can find a current version at: http://www.amazon.com/gp/product/0399144463/sr=8-1/qid=1142262617/ref=pd _bbs_1/102-7772256-4527332?%5Fencoding=UTF8 I grabbed a friend's copy and quickly compared it to the document referenced earlier on this forum - there are some minor differences in the wording, but it's the same story. My point - this is not a public work and I don't think it should be passed around as a .pdf file. Just thought people would like to know .... Todd.
