@Alfred you'd save me a lot of googling if you'd answer this question about air-gapping a computer.....
Is there a way to be on a local network (Ie small group of friends hooked up) but not on the WWW?
@eebie44 No, it is not possible to see what other members of a private LAN are doing. A private LAN is a closed network and there is no visibility between the users on the LAN. All the traffic passing through the LAN is encrypted and only the intended recipient can decrypt it.
