Private Mode lets you take part in WOW Vegas without showing your username on public leaderboards or the Activity Feed. Don't worry — it doesn't affect your ability to play, qualify for promotions, or receive rewards.
To enable it:
Head to the Edit Profile page.
Scroll to the Private Mode section.
Click Enable Private Mode.
Once active, your username will appear as [hidden] in public areas. You can disable Private Mode at any time from the same section if you'd like to be visible again.
