I went on, just now for the first time, and it worked first time.
However, it's confusing. To get your code it says "Share your License information". Well how do I know that is what it'd be for this code? Plus, getting on to the site, if I didn't put the www. before the URL it wouldn't load. That's poor.
On the plus side, the document you get is nicely laid out and straight forward.
