title: PubNub - send a "welcome" connection message
body: <p>What's the best way to handle sending a message directly to the user once they connect to the socket?</p>
  <p>Basically a &quot;The word of the day is: Frog&quot;, but is only sent to the user that just connected.</p>
  <p>My assumption is they'll join the <code>global</code> channel and also a channel that matches their uuid <code>beholden-trans-am</code>.  Users are all anonymous (this is a public stream on a website)</p>
  <p>Thanks for any pointers!</p>
