title: Should I use PASS before NICK, USER?
body: <p>I'm playing with am IRC bot (in python), and have been looking at some of the many useful examples.</p>
  <p>One thing I can't get straight... <strong>Should I use <code>PASS</code> before <code>NICK</code>, <code>USER</code>?</strong></p>
  <p>In RFC 1459, as well as several of the RFC 2810..13, it's recommend to use <code>PASS</code> before <code>NICK</code>, <code>USER</code>. Yet nobody seems to follow this practise. And the bots seem to work just fine without <code>PASS</code>.</p>
  <p>When should I use <code>PASS</code> and why?</p>
