I had one more thought for a newbie. To convince everyone you're a smoking genius consider buying a remote thermometer. Especially for pork butts (PB's), it will give you the confidence you need to remove the meat at the exact moment it's done. No opening the door to check (and risking the wrath of the collective when you submit a post wondering why it's taking so long). Also, it helps to understand what Smokin' means when he says "It's done when it's done".
Heck, I love that saying so much I say it all the time, even at work. I can't say it helps all that much there though. They still cling in futility to their deadlines.
Go figure.
