Expanding on this post about potential contest ideas, what do you think about having a "war week"? We did something similar on Philosophy, where we designate one philosopher each week, and each person who asks a question relating to that philosopher will be eligible to win a prize. It's gotten a positive response so far, and we could easily adapt the model for this site - that is, designate a war each week, and everyone who asks a question about it that week is entered into a drawing to win prizes.
It doesn't necessarily have to be wars either, any significant historical event would probably work. What do you think?
We are taking suggestions for the first war/period/historical event you'd like to focus on, so leave your ideas as answers here!
[Edit] Looks like we'll go with WWI for the first week - starting Monday 12/19. I'll make another meta post announcing the official rules then. In the meantime, keep thinking of other ideas for future weekly topics!
