Learn how to use Universal Subtitles: Step 3: http://www.amara.org/en/videos/4Q2j5WDrou35/info/learn-how-to-use-universal-subtitles-step-3

NB These three tutorials date back to October 2010. Since then, the look of the subtitling tool has undergone a few changes, but the tool itself still works in the same way, roughly: except that an editing the video title and description step has been added after the synchronizing one: thus what was "Step 3" in these tutorials now is "Step 4".
