The Prima guide for the first expansion pack of the Sims 2 has shipped to several people already, and some of them are posting a lot of information from the guide. In one big thread on the official BBS tifferoo004 has posted a lot of information from the guide. Included is information about the new careers and rewards, the influence system, changes to the aspiration system, zombies, and a lot more. On the official German site an excerpt of the guide is available for download. They've posted chapter 3 of the guide, in Acrobat format. That part is in German though. Finally, SnootySims has published two cheats from the guide, which allow you to edit and create dorms:

boolProp dormSpecificToolsDisabled [true/false] allows you to set if building tools are disabled (true) or not (false). Set it to false to allow changing of dorms

changeLotZoning dorm changes the loaded lot into a dorm. This allows you to create a residential home from scratch and turn it into dorms.
