Importing this from the DBO ticket tracker:

Simplely[sic] when Player A creates a town he is promoted from let's say [Member] to [Mayor]. Then when he leaves the town and/or is no longer mayor of a town he is demoted back to [Member].

Originally opened by Bukkit user Hockeymikey

Also be able to run a command when they become mayor. And be able to apply a special prefix to their name via vault or command.

Closing this, it's outside the scope of the project, and I don't want to focus development time on this over other issues.
