The short story
After seeing London.pm take over the YAPC::Europe 2008 stats again, I suggested starting a group called not_London.pm, which should be able to beat London.pm on the scoreboard. Due to a traitor on #austria.pm, Greg learned of this plan and consequently declared war on Vienna.pm (As a point of order, I regard the formation of !London.pm as the act of war - Greg). Which we of course accepted.
The "war" will take place at YAPC::Europe 2008 in Copenhagen and consist of three rounds of battle, "fought" by the leaders of each group, that is Greg McCarroll for London.pm and Thomas Klausner for Vienna.pm
