It doesn't exist.. I was in the process of making a fancy rank page last month, it grabbed all the members from the groups on the server and showed who was in which rank directly.
Anyway its work in progress, I had a big set back with the one of the plugins being used for that server page as it collected all the data needed for it. Now its been replacing with something much better... which is good for the server, as the replaced plugin had been causing tons of tps lag over the past 2 weeks since 1.4.6... (which is annoying bcus thats when the server had so many players on), about 19x more lag than NoCheatPlus uses in cpu for all its cheat checking, that's a known to lag servers at times with lots of players on.
To give you an idea of the lagg....
Total: 3134.973s (this is just a total amount of time all plugins on the server have used in cpu over the length that this was timed for)
Array

[PlayerLogger v2.9] => Array

.... just to put it in perspective...
[NoCheatPlus v3.8.7-beta-b294] => Array

[Total] => 121.873sNow NoCheatPlus is the laggiest plugin on the server.. which is actually not much lag at all
