NetRPG is based on Chat 2.0.6 by Nathan Neulinger, with earlier versions by Peter N Lewis
"Did you used to play Role Playing Games in the old days, but can't anymore because your fellow gamers have moved off to jobs or grad schools in other cities? Well, you're in luck! You can still play RPG's (especially D&D, copyright by TSR) with NetRPG!"
NetRPG is an expansion on Chat 2.0.6, with many added features that make it suitable for playing RPG's over the internet.
