Guild Wars officially opens Guild Wars Wiki. Now you have a source for loads of information about the game.
After a few weeks of early preparation, we're now eager to throw open the doors of the official Guild Wars Wiki. We invite you to join the GWW community and help us create a wonderful resource for Guild Wars players--now and into the future. Set up a user page. Edit an article. Create a new skin or upload images to flesh out one of the articles. Whatever your level of expertise, you have a contribution to make on the GWW! And if you'd rather simply use the GWW as a resource, you're very welcome, too. Dive into the Guild Wars Wiki through the main page, found here.
