@CHOWN

@chown <object> [ =<player> ]

Changes the ownership of <object> to <player>, or if no player is given, to yourself. All players are allowed to take possession of objects, rooms, and actions, provided the CHOWN_OK flag is set. Mortals cannot take ownership of a room unless they are standing in it, and may not take ownership of an object unless they are holding it. Wizards can chown almost anything except objects owned by a higher level wizard.
