Using the Crazy Egg Dashboard

1. I've loaded my dashboard page, but I'm really confused. What does all of this mean?
2. Why would I need to delete a test?
3. What does "Test a new version" do?
4. How do I add a new page to track?
5. I lost my code - how do I get it back?
6. How do I know how many visits I have left on my account each month?
