We are running an SOS (Semantic Open Space) group with the main discussion on Facebook and a running Google doc for Issues, Causes, Effects and Proposals.
More details of the meeting and the SOS structure. SOS is a syntax designed to capture community Issues and Proposals so that they can be shared with other communities.
SOS was designed for Open Space type meetings but it seems to work reasonably well with a virtual community.
Feel free to join the FB group or comment on the Google doc
