Nicholas from Amara writes, "Yesterday afternoon, the social coding platform GitHub invited their fans to collaboratively translate their how-to videos using open-source platform Amara.org. In less than 24 hours, 150 volunteers created 40 translations across 18 different languages. On their blog, Github wrote: 'We think it would be cool if people all over the world could enjoy our videos, regardless of what language they speak. So, starting today, we're inviting anyone who's interested to help us translate our videos via Amara's Volunteer Platform.'"
