Well, due to the overwhelmingly positive (and fast) responses, I will begin this shortly. I am expecting to have the first question posted either Sunday or Monday, so keep an eye out for it. Aside from the final question that will be PMed to the five finalists, I will not announce in advance when a question will be posted. I'm doing this for two reasons. First, it will make the winners more random. Rather than having ten really excited people waiting for the question to be posted and then answering immediately, I would expect that a variety of different people will have the opportunity to try. Second, I don't want to set a deadline for myself and then not be able to meet it.
I have also added some information to the prizes section in the first post that you may want to check out.
