I asked Chris about that before. As far as I know this event will be open invitation. (Members who have joined us before are welcome. New members who haven't yet should state their interest.) Chris also mentioned that Charles might want to start something earlier, to which I responded, "That's fine. Just expect me around 8 or 8:30 on Saturday night." At this point I'm not sure what's going on. Since Chris and Charles were the ones primarily discussing this, especially since Charles was going to be hosting the event (I believe), I had hoped they would confirm the details.
