Andy Salisbury or Skaarjonic, one of the editors at the magazine, says:
Andy also says you should make sure that everyone in the picture is OK with having their image published before submitting.If you've got any pictures of a real life meetup that you and your guildies had, we'd love to see them! Head on over to our forums at Wowhead, tell us about the get together, and send your pictures to firstname.lastname@example.org. Who knows, you could find yourself published in the next issue of the World of Warcraft Official Magazine!
Again, these are real life photos and not the triumphant screenshot of your guild's Lich King kill. It's really cool you killed him. And I'm sure the screenshot is awesome. But it's just not what they are looking for, sorry. To retierate -- Azeroth: Nay. Earth: Yay!
