That was nice help. Now we move to next set of questions, dealing with actual action.
1. When the game starts, I presume that a role will be given to me. Do I have to reveal my role to anyone through personal messages or role plays? (How does revealing or keeping secret the role affect the game?)
2. Can I contact my team-mates (i.e. my side players) through PMs and decide on voting?
3. Are there any chances of getting killed in friendly fire? (Suppose I vote for someone and he turns out to be my team-mate? Is it possible at all?)
