As the site states: Part intranet, part do-it-yourself project with a kick of open source hotness. Open Atrium is an intranet in a box that has group spaces to allow different teams to have their own conversations. It comes with six features - a blog, a wiki, a calendar, a to do list, a shoutbox, and a dashboard to manage it all.

But you're not limited to just those features. Open Atrium is completely customizable. If you want a feature that's not on that list, you can add it yourself. Read the documentation, specifically the How to Build a Feature section, to find out how to do it.

Want more features? The fun really starts when people start sharing the features they build for their own Open Atrium with everyone else. Then everyone doesn't just have access to six features but also a bunch of others that are easy to plugin to the basic Open Atrium package.
