In this picture the player level range has been erased and REFRESH clicked. Notice the list is longer. You can also type another zone-territory name between the quote marks, then REFRESH to get a listing for that zone. You do not have to be in the zone you query. Find the other zone-territory names from the world map drop down list. In this Who List you can change the display to show Guild by clicking the drop down list (where it says Zone) and selecting Guild. You can see who is not a member of a guild. The Who List allows you find other players to group with for difficult quests, or find a special class player you need. Click picture for full image.
