First, read the Roles section for details on individual jobs. Wikipedia also gives a decent outline of the game, though it's not exactly how everything works here.
Now, onto the meat of the game. You are living in a normal (or maybe not so normal) town with a dark secret. Now, it's come to light that a handful of your fellow citizens are out to murderize the rest of you. Shocking! Thankfully, you are many and they are few, so clear thinking and nerves of steel could keep some of you alive.
The game is run in three distinct parts. The first is investigation. It's the Cop's job to select an unknown to investigate. Anyone can give input, but ultimately the decision belongs to them. Following the investigation, a story post will reveal the allegiance of the target.
Next up is the lynch. Every member of the group gets to vote on a person to eliminate. Note, this includes all special roles, so the mafia can often steal a divided vote, or force a tie that's decided by a random number generator. And this isn't an election you can afford to skip out on. If a player fails to vote, the coma rule can be invoked after 2-3 missed votes. A random comatose player can be killed periodically, usually every lynch. Note that once all player roles are known, the Cop and Bodyguard can no longer vote. The allegiance of the lynched person (if unknown) is revealed following the lynch.
Finally, there's the whack. All special roles with killing abilities as well as the Mafia select players to whack. That means the Mafia, Psycho, and Vigilante can all kill someone. At the same time, the Bodyguard will get a chance to foil an attack by protecting a person of their choice. In the event of a successful, a clue to the perpetrator's identity will be left in the post, usually a reference to profile information on their first page of images, journals, or interests. If multiple groups target the same person, the first one to get the vote in will be the one who the clue will point to. If the whack is blocked, no clue will be provided.
While special roles may have different victory conditions, the general mafia and civilian roles are as follows: Civilians must eliminate all mafia before they're all killed. Mafia must eliminate enough civilians so they comprise an equal or greater voting block in the lynch. So if there are two mafiosos and two civilians, the game would end if all roles were known (voiding the votes of the cop and bodyguard). However, if one or more was unknown, the game goes on.
All votes must be sent by private message before the deadline. There are usually three rounds a week, with two days between each to get votes in, so there's no excuse for being late. In the interest of clues, once the game starts you cannot change your profile, delete images/journals, or post an excessive number of images/journals. These are all used by the DM and making the DM annoyed with you will often result in bad things happening.
