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