title: Who actually uses a full JID?
body: <p>When logging in to an XMPP server via smack, I only send the userid/password combination.</p>
  
  <p>Do server components actually use the "resource" parameter in a full JID?</p>
  
  <p>e.g. ali@someplace/resource</p>
  
  <p>What are the benefits of sending it?</p>
