Our expenses for the quarter were down slightly, although our sales and marketing expenses have increased compared to the same quarter last year, primarily driven by additional spending to acquire 2010 travelers, as well as the beginning of our marketing spend for 2011 travelers.
With our core People to People Ambassador Program’s operations, we have focused to a greater extent on our largest and most important product, the Student Ambassador Program, and are seeing some progress there.

This modest growth was expected and in spite of turning of unprofitable marketing and Google AdWords, which drove traffic but not revenue. Our revenue per 1000 unique users, which is the measurement that shows our efficiency in generating revenue from website traffic was down 16% from the comparable period last year. This decrease was also expected, and was the result of the prior mentioned ad partner contract renegotiation.Discovery Student Adventures will also start operating its 2010 travel programs this quarter.
