We're happy to announce that through the wonders of modern gnomish engineering, you are now able to change your characters' names. Finally, you can turn the moniker that seemed like a good idea at the time into something more befitting your true standing in World of Warcraft.
Visit Account Management to begin the paid character-name-change process. The fee is $10 per name change. As with our recent addition of voice chat to the game, this feature is being rolled out across all realms in several phases. The first-phase realms are listed in this forum post. Enjoy this new feature and the subsequent effect that your bold new name will have on friends and foes alike.
