title: Receive message from slack bot
body: <p>I am quite confused on Slack bot using Python. I want to be able to receive messages sent to by bot:</p>
  
  <pre><code>client = SlackClient(API_TOKEN)
  
  if client.rtm_connect():
      while True:
          print client.rtm_read()
          time.sleep(1)
  else:
      print "Connection Failed, invalid token?"
  </code></pre>
  
  <p>Then I send a message to my bot in slack. But I don't get the message. How do I start sending message to my user?</p>
  
  <p>Also, is it possible to include the bot in all channels? So if I'm in any channel, I want to be able to say <code>@myBot args 123</code> </p>
