  34 <PRE>To quote the RFC (RFC1459 4.4.2):
  35
  36    The NOTICE message is used similarly to PRIVMSG.  The difference
  37    between NOTICE and PRIVMSG is that automatic replies must never be
  38    sent in response to a NOTICE message.  This rule applies to servers
  39    too - they must not send any error reply back to the client on
  40    receipt of a notice.  The object of this rule is to avoid loops
  41    between a client automatically sending something in response to
  42    something it received.  This is typically used by automatons (clients
  43    with either an AI or other interactive program controlling their
  44    actions) which are always seen to be replying lest they end up in a
  45    loop with another automaton.
  46
  47 While this section doesn't explicitly say &quot;automatons MUST NOT send PRIVMSG
  48 messages&quot;, the last sentence is, IMO, semantically equivalent to at least
  49 an RFC 2119 &quot;SHOULD NOT&quot;, as in &quot;automatons SHOULD NOT send PRIVMSG
  50 messages, lest they end up in a loop with another automaton&quot;.  That's
  51 more than enough justification in my eyes to not add a PRIVMSG sending
  52 option/command.
  53
  54      In any case, if you do want to send a global PRIVMSG, you can always
  55 use /msg $*.whatever.net as an oper.
