The simplest way I can think of would be via a forum (message board) of some sort. Either that, or we could always do it via IRC if we could get a room.
Although you still have to create a basic character. If you want, there are a few basic things you'll need. Try working on a character background, and your basic character appearance. Get those down.
Also, you'll want to choose a virtue and a vice. (Pick from a the seven heavenly virtues and seven deadly sins)
Virtue and vices effect how you get back willpower. (Willpower points are special points. If you really want to make something happen, you spend one to add +3 dice to making an outcome happen.) You can get points from acting according to your virtue or vice, so it doesn't force you to be good or bad. It just effects how you get the points, and when during gameplay. Although, doing good/bad things also have obvious storyline effects.
Start with that.

(Also, if you know of any reliable message board services or IRC rooms, I'd be appreciative. I want to start settings this thing up)
