A non-linear, non-chronological discussion forum. Similar to the forum activity, but focuses on straightforward question-and-answer discussions. Additionally, users rate posts and gain a rating score ("reputation") by being rated by other users. Users who have started a discussion can mark an answer as helpful; and teachers can mark a post as a (correct) solution to the posed question.
