I prepartied while trying to fix Elftown's and Elfpack's network problem. Elfpack's server had gotten new IP-numbers after the network rebuild and I had to search through the local network to find it (As I can't log into it directly I didn't know what IP it had). But I managed to find it and update the DNS before we had to go to the international evening at HG.
It was freezing cold! Some data suggest only minus 8, but local thermometers showed way less.
