Here are a couple of documents, one with excerpts from and links to writing by Barrett Brown about Project PM, another with links to videos by Barrett. You may need a Google account to open them; it's free and you don't have to use it otherwise.  I also recommend following these folks on Twitter: barryeisler, BarrettBrownLOL, mmhastings, jeremysapienza, jricole, jeromestarkey.  I am a retired guy from Chicago who works with Barrett on Project PM.
