PLATO: The Emergence of Online Community Copyright © 1994 by David R. Woolley An earlier version of this article appeared in the January 1994 issue of Matrix News. Overview Two decades before the World Wide Web came on the scene, the PLATO system pioneered online forums and message boards, email, chat rooms, instant messaging, remote screen sharing, and multiplayer games, leading to the emergence of what was perhaps the world's first online community.

One of the most haunted buildings on campus is said to be Pennsylvania Hall, a large building with stately white columns. Perhaps the most famous story connected to the time of the battle was related by author Mark Nesbitt. The Devil’s Den...
