I (and I'm sure, several others) will be on IRC at around noon this Saturday for blitzy goodness. I'll have around 6 hours, so we can get in a good one.
You can access #dominions on irc.gamesurge.net; there is also a java client thing on
www.gamesurge.net, so there is no excuse
EDIT: Noon here = 19:00 GMT
