This looks cool. Count me in! I'll try to get an application up tomorrow.

My initial question, that'll shape my choice, is what happened to Canada? Still in existence? What else is different beyond the American civil war?

What happened to Canada and the rest of the world is up to the other people applying unless they officially ask for something. 
For example: You could have a story about Canada conquering Alaska.
