For consistency, command-line keywords (such as SPLIT=nnn or PW=xxx) are
allowed on every command, whether or not they appear to make sense for the
command in question. There are only a handful of exceptions and they are
special commands meant to be used by scripts rather than people. So, you can
do HELP PW=xxx even though the HELP command does not require a password. You
can always specify SPLIT=xxx.

If you use the web interface and want the results of a command to be
e-mailed to you, prefix the command with the word MAIL, for instance:

MAIL QUERY XYZ-L FOR *@*
