This project is not maintained anymore!

Domain zen-wiki.com is now shut down, but the site and all data is still available at https://zen-wiki.appspot.com . If you use this servise it's recomended to migrate to somewhere else. I cannot guarantee that the site will be available at https://zen-wiki.appspot.com indefinitely.

Note that the project is open source and you can deploy a replica of it to Google App Engine, if you want.
