I called the meeting, but actually someone else first called it a "Happening". I think it was Ross. Does anyone remember? Anyway, I think that's the right word for it too.
BTW, for all of you who didn't participate in the first two calls, it may be hard to understand why we are all so excited about a simple conference call. I think the multi-modal aspect and the integration of the Wiki is a new and exciting development. Ross does a good job explaining it on his blog.
