Here's another game for the community to play:
One person asks a trivia question that they know the answer to. Then, other members will try to guess the correct answer. If the guess is correct, an edit to the question post will be made to say that the question has already been answered and by who. In turn, the first correct correspondant will in turn ask a question of their own. If no answers can be found after a period of three days, the answer should be edited into the question, and that person can ask another one in the same post.
For example:
User1: Who is the Red Hulk?
EDIT: User2 got the answer, right. It's Rick Jones.
User2: Rick Jones.
