Like GameSpy did with the previous two expansion packs for the Sims 2, they have now started a series of articles called the SimPrentice. They talk to Grubbs, "a full-time slacker and part-time entrepreneur," who has set up his own salon in the Sims world, in his parents' garage. The article has several screenshots, including some of the interface. To see those, check out the screenshot gallery of GameSpy. Naturally for more details, you should read the interview.
