Hey guys, Ive noticed that to ban people from servers you need a leader present to ban them via rcon, i would suggest using PHP rcon, it allows some rcon tools to be used by trusted users without giving them the rcon password for the servers, and it is configureable to multiple servers, it looks what each person does by username instead of ip address to make finding people a lot easier. this also displays guids and can work with punk buster. This is a web interface, so you can log in from any computer.
