Obsidian Portal - http://www.obsidianportal.com - is a free web service that allows players to create campaign websites for tabletop role-playing games. Rather than trying to automate the playing of the game, Obsidian Portal provides tools to help facilitate the storytelling. Every campaign gets a shared blog/wiki to showcase their story, as well as integrated tools to help track NPCs, locations, treasure, and all the other minutae that makes up an RPG. After all, the story is the game!
