It's a simple idea. In the sheriff's office, each player can make the choice that if attacked, the assaulted will automatically hang up a poster of "wanted". As follows: Have an option to apply a form where the player imposes the reward, the amount the player want, if you want either by duel or fainting. When the player is attacked, automatically the poster "Wanted" hangs in the office, with the amount of the reward posted by the applicant. And the money from the "wanted" is automatically removed from the player's account. If the player does not have enough money, the poster does not set.
