Exo Collaboration Suite has just reached our demo server.
It is based on the freshly released CS 1.1 beta4 that is already available for download on OW2. This live demo is still beta and will be updated when we release 1.1 final. Until that, we will be happy to hear some feedback at email@example.com.
Enough talk, jump to the demo : http://cs.demo.exoplatform.org
