Some students said that they couldn't access the course page showing the rank ordered list of students contributions, so I'm attaching a static image of the page here. You can also see your up-to-date total by going to your profile page, which lists your contributions. By the end of the semester you should have approximately 26-30 contributions that represent activies in the course discussion forums (i.e., not uploads of homeworks), assuming two contributions a week for at least 13 weeks of the semester.
