Project 1999 - Miscellaneous: /who lfg not working

It is Classic/Kunark (from 08/17/2000 patch notes):

www.tski.co.jp/baldio/patch/20000817b.html

Code:

Players can now indicate that they are "looking for a group" by typing /LFG. This 

command will flag your character in both zone-specific /who lists, and the 

server-wide "/who all" list with "LFG". The LFG flag will remain active until 

you either enter a group or log out. Players can search for other players 

who are LFG by using filters in the /who command. For instance, to find 

rangers between level 40 and 50 who are looking for a group across the 

server, type "/who all ranger 40 50 lfg".
