In addition, each clan permission will have an associated title that any member with that permission can choose to display if they so desire. For instance, a clan member with permission to recruit members can choose to show the "recruiter" title. Military ranks will remain in the game, but they are now governed by PvP performance and each new military rank is granted automatically upon the completion of specific goals. These ranks have no bearing on clan permissions. The full details on the new system are available for perusal over at the Darkfall official site.
