Rock your everyday

While searching for drupal based application, I have found Open Atrium and it looks to me very useful for different team based works. 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. Enjoy drupal!
