Caucus is an open-source, web-based eLearning and discussion platform. It is used in universities, non-profits, and companies wherever learning, conversation, and coordination must happen together. 

Flexible and free, yet commercially supported, Caucus is easy to install, and easy to evaluate.  See "What is Caucus?" for a frank description of its capabilities, and what it can do for you.
