Besides the organizational support from the next two SMOFCons, we're able to run this event using some of the "infrastructure" set up by CoNZealand for their programming, which is why you'll see their name in the URLs.
As of today, there are more than 200 people signed up for SMOFCon 37¼. Membership is free, but advance registration is required. If you sign up, choose "Registration," not "Program Participant," as the latter is for people who are representing Worldcon and SMOFCon bids and seated conventions or who have been invited to be on a program item.
I reckon that next Saturday is going to be a very long day for me, as I need to be on deck by 04:45 Pacific time as part of the organizing committee. Although I normally am up at 04:30 for my Day Jobbe, I don't usually have any meetings until several hours later, and my early start has to do with some tasks I must do before anyone else starts work, after which I usually go shower and grab breakfast. I don't think it would look good for me to show up at the start of the convention in my bathrobe, so I'll be up earlier than usual in order to be ready for the start. And I might just take some sort of break during that sixteen-hour convention if I get a chance.
