Dimdim was made available primarily as an enterprise edition and as a Virtual Machine appliance, but an
open source community edition has also been made available to developers under the
GNU General Public License (GPL), giving them the option to install and host Dimdim in their own networks. The most recent open source version, released in December 2008 and hosted at sourceforge.net, is V4.5 "Liberty". However, no installation instructions were provided, and the software had several arbitrary limitations, leading some to describe it as "crippled". Distributions of the system for the installation to several OSes, Virtual Machines and the corresponding documentation are available in several archives on the
SourceForge.net Dimdim site. Dimdim can be integrated with the e-learning platforms
Moodle,
Claroline and Docebo , the collaborative suite
Zimbra and the
CRM software
SugarCRM. Unlike Dimdim's web-hosted services, the Dimdim open source server does not restrict the number of attendees or simultaneous meetings allowed. As of December 2010, at Dimdim's website, there was no download available for the open source version and the only way to download it was from SourceForge.net. Dimdim's acquisition FAQ states that the company would no longer be contributing to the open source project. As of January 2011, an open source fork called had been started. == History ==
