The original idea of the "Submit a Question" feature on TriviaFix was for players to be able to challenge others by submitting there own sports trivia question and answers. Very quickly I realized that many were trying to submit trivia questions that they didn't know the answers to. I am thinking of adding a feature that would allow for this type of question - but until then you should try some of the sites dedicated to this like Wiki-Answers or Yedda (recently purchased by AOL).
Here is one that was submitted today:
"Last week the Philadelphia Eagles were double digit favorites this week they are double digit underdogs has this happened before in the NFL?"
Great question- if you know leave the answer in the comments, or better yet submit it as a Football question on TriviaFix.
