Looks like it's not gonna happen anyway. It's 18:15 GMT now but the live chat ... isn't. There's a few people logged in but no conversation and no sign of the sun people.
Oh well. Back to work I spose.
EDIT: found a different clock that also claims to be GMT, only it's showing an hour difference. Arrgh. And I'm running linux, so I don't have access to a real clock
(the kernels have a software clock that is broken, but you don't get to use your ultra-accurate hardware clock instead, just in case you are running an 8086 with an inaccurate clock. Clever).
EDIT2: Apparently you can't type anything until the official moderator arrives and allows you to, but it doesn't tell you this in the client
