Open Atrium

We are currently trialling Open Atrium for use within Organic Design to manage groups as part of implementing our Platform specification.

	Open Atrium is an open source platform designed specifically to make great teams communicate better. An intranet in a box with: a blog, a wiki, a calendar, a to do list, a shoutbox, and a dashboard to manage it all.

We have investigated a number of Drupal-based extensions to use for implementing our ideas and Open Atrium is one of the leading solutions so far due to its support for setting up multiple groups within one system, allowing us to set up simple trust groups within it.
