I think this will be the last update regarding the Ranking System. We have sealed all the possible Immunity and Rank holes so we should be good for a few years.
3 New ranks have been added. Epic Admin - You gain the ability to play Source based music, make props, change Game Modes and a few new Fun Commands. Leet Admin - You gain the ability to change many cvars which you could not with the lower ranks. Nod Admin - You gain the ability to change even more cvars and config files.
Each admin rank gains more and more Immunity. P.S I hope this really is the last ranking system update.
