This seems interesting. I was in one of these some time ago, but it never took off. I'd love to participate if possible.

Questions:
1. How active does a player have to be. My schedule is pretty tight these days and given my track record RPing i can probably make a decent length post (A good few paragraphs) twice a week.
2. What sort of roleplaying level are we thinking of here?
3. With regards to all the characters I'm assuming the player characters are "key" characters that make stuff happen, and have some sort of special characteristic.
4. This is kind of a suggestion more than anything, but wouldn't it be ideal for each character to have a set goal that they wish to accomplish, and have a set community goal, a form of crisis that everyone is also trying to accomplish, but the personal goals may get in the way.
	* For Example let's say we have "Nurse Fred" his set goal is to secure a clinic for the sick and injured, but the current goal is to find food, immediately, as such he has to set aside his own plans for now to go with the group.
5. This is kind of a wild guess, but i'm getting a Dead of Winter vibe from this RP.
