Instructions
Open the "World of Warcraft" game and log in to your character account.
Type the following slash command to find a user and press "Enter":
/who gamer_name
Replace "gamer_name" with the user you are searching. This command uses the exact username. If the user is offline, no results are shown.
Type the following slash command if you only know part of the gamer's character name:
/who gamer*
In this example, all names that contain "gamer" are shown. The asterisk acts as a wild card character to search for several users at a time.
