I need to delete the following username from my mailing list:
 
However, when I send a mail message to listserv, it comes back with the error:
 
> delete  fibrom-l [log in to unmask]
 
Invalid option - "[log in to unmask]". The valid options are GLobal, LOCal
and TEST (minimum abbreviations shown in upper case).
 
I'm not on the bitnet so I can't edit the file directly.  Any suggestions?
Thanks.
