Currently, I require my students to submit one post and one reply to another students' posting. Speedgrader does show both the posting and reply, but does not tag which one is a post and which one is a reply. I have to manually keep track of this by viewing all the discussions and finding the indentation level which is pain in the behind. Sometimes the indentation is not obvious. This makes grading a difficult task as I have to keep a separate spreadsheet to track postings and replies.
