This may be a unique request, but here it goes:
I want to setup posts with a "Yes/No" option. There is a correct answer to each post. I want logged in users to be able to vote "yes" or "no" on these posts. Those users that are correct, get a point, or something similar. I then want to be able to provide a list of users who guessed correctly on each post. We should also be able to show which users were correct in aggregate on guessing on all posts.
Post title: Is California A State
Users can vote Yes or no. After correct answer is entered for the Post, the users who guessed correctly get a point.
