<TT>@who <player> [<player> ... ]</TT>
The first form lists all of the currently-connected players, along with the amount of time they've been connected, the amount of time they've been idle, and their present location in the MOO.
The second form, in which a list of player names is given, shows information for just those players. For any listed players that are not connected, we show the last login time instead of the connect/idle times.
@who refers to the @who_location message (see ?messages?) on each player's location in order to determine what should be printed in the location column. The default value is the room name.
?@where? -- Information on locations and ranks.
?@wizards? -- Stats on the wizards and guardians.
