Quote from Gordon from EQ saying this feature wasn't available.
Q: >>>
A kind of "/who all zone" command, that would either list, or at least give a count of the players in a specific zone (without one being in that zone). In an overcrowded environment, it would save casual players a great deal of time if they could look to find a less-used zone to hunt in without having to travel to it first.
A:
We're still looking into the possibility of this. We like the idea and think it would enhance gameplay for those that choose to find greener pastures.
