actually USwest is very active (clan notd), USeast is rarely active (clan zap), Northrend (clan notd) is active but only for notd3 (which is not played much outside of northrend).Just got back into Warcraft 3 and want to play some NOTD. It's completely dead on BNet.
I saw you on GGC the other day. Nice to meet you. btw, where are you from?
