Open Atrium is an open source intranet and team portal application built on Drupal. I thought it looked quite interesting and so I set up my own install of it.

Open Atrium allows the site administrator to create and configure private 'Groups', each with their own section of the site and can be set up with the following features:

• Blog. Posting news for the team.
• Calendar. For scheduling team events.
• Case tracker for projects (Bugs, feature requests etc). It's a highly simplified one, but that's a good thing.
• Notebook. A simple hierarchical wiki, could be used for a knowledge base.
• Shoutbox. Basically a mini Twitter clone. Kind of pointless I think.

I'm trialing it out for managing my hobby and collaborative projects. If you want access to my Open Atrium site, even just to have a tinker in it, please let me know.
