What happens if someone can like...randomly show up, but hasn't told anyone? Like is miraculously able to come out to CA and happens to be there that weekend?

(BTW, as for the "mad" Eastern convention, if Paul and Sheep and I can have a LAN, I think we can pull together something bigger. Anytime someone drops a clue as to their wanting one, I'm in. Not to mention we've got Boston in our backyards.)
