Okay, I guess there's enough interest. Now to settle on a time. I think I want to do this on a Sunday afternoon, since this is least likely to conflict with plans. And I want to do it early enough so that people can do other things with their day. So I'm thinking some Sunday starting at noon, schedule it to go 2 hours, to give time for things to not go smoothly.
If I do it at my current place, it looks like it will have to be on May 19th. If it's after we move (on the 31st), then I don't think I can do it at our new place, since we will have considerably less room. In that case, I'd need to find someone with enough space willing to host. I'd like to do it sooner than later, so the Sundays in June that look relatively free are June 9, June 16, and June 30.
Anyone have comments on any of these dates?
