bgneal@544 3
bgneal@544 4 The phantombrigade application doesn't have anything to do with SG101. It is
bgneal@544 5 simply some useful web services that we provide to the gaming clan Phantom
bgneal@544 6 Brigade. Rather than create a whole new website we just use the infrastructure
bgneal@544 7 of SG101.
bgneal@544 8
bgneal@544 9 Current we provide a TeamSpeak 3 status view for the PhantomBrigade.us website.
