As till today, we have worked on non-profit terms. All revenue (very minute) has been from donations for the entire system, its popularity n development as well as Yahoo Adsystem revenue. We don't have a "Profit" function as is. The reason of the high sale is we've set it up so that it can definitely get any business good profits under their control. As of now, I havent really looked on the financial terms except my perception of the teams hard work, effort of the last 4 years ... no stats n details ...youd have to value it yourself and see if it worth it and if you can make it earn you more.
