How much would it cost to officially purchase the website Yahoo Answers?

I have inherited about 2.3 Billion dollars from my grand father. He is about to die in about 5 - 14 months and after he dies he still has another pay roll coming for me which is estimated about 13 million dollars and I still have $4976 saved on my foundation account. I was thinking on spending all my money on literally purchasing the site Yahoo Answers and do whatever I want with it. How much does it cost?
