The much hyped Basecamp collaboration Service allows users to export all their data to a XML file. These files can now be imported to Collabtive, offering a viable alternative for people trying to move from proprietary Basecamp. Collabtive takes on Basecamp to create an Open Source alternative in the collaboration space. The project has been started just 5 months ago, and was downloaded more than 10000 times since."
