* With Grid Comms up in the air.. I decided have the friends module update you when your friends come online if they're at least a child agent on the sim. offline status works the same also. So does Instant Message.

* This is until Grid Comms matures a bit more on this.
* This should also work in Standalone as it uses the IUserData interface.
