title: Free online application for doing scrum on rails
body: <p>What is the best free online software to help do agile development and management on my ruby on rails application?</p>
  
  <p>What I am looking for is an online form that multiple people can interact with with the ability to do:  </p>
  
  <ul>
  <li>Planning poker  </li>
  <li>Iterations/sprints  </li>
  <li>Velocity calculations/predictions  </li>
  <li>Backlog prioritization  </li>
  <li>Stories with point values  </li>
  </ul>
  
  <p><strong>Bonus:</strong>
  And maybe a way to integrate with github</p>
  
  <p>I have tried scrumdo but just wondered if there is a better free application.  </p>
