How does it work?

Leaders have the ability to create ranks and give them permissions to perform several actions inside the clan.
Unlike /clan trust, ranks with permissions allows leaders to have a finer control of who can do what. Ex.: A rank can handle invites (invite permission), another takes care of moderation (kick permission), etc

Suggestions of ranks

Coleader: helps take care of the clan; permissions: all
Treasurer: manages the clan's bank account; permissions: bank.balance, bank.deposit, bank.withdraw
Ambassador: manages the clan's relations with other clans; permissions: ally.chat, ally.add, ally.remove, rival.add, rival.remove, war.end, war.start
Recruit: a member in trial; permissions: stats, kills, mostkilled, rank.list
