I actually just used the login name. Some of my users used some long display names so I tried the login first. So if I wanted to add one for myself here it would be something like..
if ($thisline[2] eq "tw1112")
{$custom_title = "Hello Everyone";
}
Because tw1112 is my login and my display name..and hello everyone is my new status.
Then that should be it...save the file and upload it in ascii.
