This document describes an online seminar room called Big Blue Button. It has modules for users and listeners, a whiteboard, and chat functions. There was some lag discussed, and fewer interactive tools than other systems like Elluminate. Benefits and challenges of online communities of practice in higher education were discussed. Identity, literacy and community in partially synchronous distributed learning environments were explored as topics, and how the environment interacts with these topics. Evaluations provided both positive feedback on the productive discussion and useful learning environment, as well as technical difficulties experienced by some participants.
