It came from the Blog isn't the only game in town, of course. The Defias Brotherhood hosts a few RP-PvP events, as this video shows. The Spreading Taint and The Stonewall Family guilds march in a pride parade every year. Big Red Kitty's charity run for Ezra was so much of a success that they crashed the server and were asked to end the event early. Many more events are held in WoW each month, and some realms are more active than others. You can check the Community Events and Creations Forums for events you may be interested in.
