As simple plugin that promotes players from one group based on conditions from several plugins such as stats/achievements , iconomy, joerep etc ideally it could read from a config text file where users could write out 1:$player:$group:$condition:$value:$broadcast text example: 7:$player:Regulars:$stats.timeplayed:$1day:$player has been promoted to Regulars for playing a day! entry number: 7 player to be promoted or $player as default: any group to be promoted to: Regulars what condition is to be met: time played (pulled from stats( value of that condition: (a day / 24 hours/ however many ticks who knows...) text to be broadcasted to everyone: ... **note that that condition $player can be left $player for any player or it can be set to a specific player to ear mark that player to become admin once their joe rep it high enough etc.. the it would ahve basic commands to add edit and delete in the console. i think flatfile would suffice.
