Who off

["William S. Galkin" <wgalkin @ lawcircle . com>]

Hello all - I assume that this is a basic question -

Can I as listowner turn off the who option under 1.94? Now I am not
working directly with the server, so I would need to send a command,
like when I change the password. 

Can a command string from me turn off the who or does the system
administrator have to do this? 

Thanks for any help.

Bill
