I propose, as an interesting activity that any user can take part in, that we have a trivia quiz, that is hosted on the chat feature of the wiki.
Basically, the idea is, somebody is chosen as quiz master, and goes through various pages of the wiki, looking for interesting pieces of trivia posted on each of the trivia sections of the pages, and turn them into questions.
Everybody that wishes to take part will be come onto the chat at a certain time of a certain day, and the quiz will begin.
The quiz master will post the questions on the chat, and basically every other user on the chat has to either go through the wiki, or their memory banks, to come up with the answer, the person that can post the answer on the chat the quickest will win the point. After so many questions, the user with the most points will be declared the winner.
I was hoping that if I posed the idea here, then people would be able to post comments on whether they think it is a good idea or not. If enough people are interested, then we can take this further. If very few people do, I won't bother.
