title: iCal - Beginner Tutorial and Docs?
body: <p>I am working with an existing ical file at work.  I'm not sure who is creating it, and I would like to become more familiar with ical before I contact them - so I can have an intelligent conversation.  </p>
  
  <p>Can someone point me to a good beginner tutorial for iCal?  </p>
  
  <p>Most of what I've found so far has been very vague, and assumes too much user knowledge.  I need something that covers the basics (tags/parameters, setup, publishing, etc), but also explains things like synching iPhone, Android, and Blackberry with calendar updates on the server.</p>
