How do I view my project RSS feeds, I keep getting an authentication failure

RSS feeds are not public, so require authentication. If you are logged into ScrumNinja, you can view RSS feeds in your browser. To view RSS feeds in other programs, you'll need to use your API key.
This token is unique to your account, and can be created/destroyed at http://scrumninja.com/user/edit#api
Add this key to the end of the RSS url that you would like to view,
e.g. http://scrumninja.com/projects/##.rss?api_key=XXXXXXXXXXXXX
