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 May2013 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.
