I wanted to explain our thinking about these forums, and why we haven't forced people to be subscribed. Because CALMEt Online is a larger event, we were not sure that all participants would want to be subscribed to ALL discussions in ALL sessions through November, so we did not force subscription except to the News Forum and for the final forum in this session on Discussion Forums.
If you prefer, I could make a change for everyone who might not know how to subscribed. Just let me know.
