Radiant is a no-fluff, open source content management system designed for small teams. It is similar to Textpattern or MovableType, but is a general purpose content management system (not just a blogging engine).
Don’t want to get into a whole installation just to test it out? There is a live demonstration site available for you to experiment with, the “Username” is “admin” and the “Password” is “radiant”; and don’t worry about breaking anything the entire demo site is reset to a pristine state on the hour.
Found a bug? Can’t get something to work? Having a hard time understanding the documentation on the wiki?
The best way to report a bug or request a feature is to write the fix or enhancement and then send a pull request. If you’re not that familiar with Git or the Radiant codebase, you can also file an issue.
The mailing list is a great place to ask questions about Radiant.
Having trouble using or installing Radiant? Want to share a success story? You can chat with members of the user and developer community in real time in the #radiantcms channel on irc.freenode.net. You’ll need an IRC Client. There’s a nice list of them over on the Ruby on Rails wiki. Additionally, there is Freenode Webchat which gives you an IRC Client in your web browser.
Due to incessant spam the Radiant Users page has been removed.

The best way to learn about Radiant, by far, is to read the source. Ruby is extremely easy to read and Radiant is a straight forward Rails application. So don’t be afraid of the source, dig in! The app directory is a good place to start.
