It wasn't quite a time of innocence, more like a time of trust-through-ignorance. The entire network was built on people who relied on each other for connectivity, software, and support. I once got slapped down for suggesting that we put passwords on an astronomy computer: "What have we got to hide?". (Turned out that someone had set up a bulletin board server on that system, without anyone's knowledge.) Cheers, -Cliff
