Macworld 2010 Registration Code

The iPhoneworld Macworld 2010 organizers are giving away a free night's stay at the San Francisco Marriott to people who refer five friends to sign up for at least a free Expo Hall-only pass using the following priority code: BN958. It's a clever idea to get word of mouth, and people to potentially attend more than one day during February 9th through 13th next year.
