In some courses students can see the postings of other groups but can only post to the group to which they are assigned and in some cases students are assigned to more than one group. If you are unable to locate the posting of your group members in a discussion forum, first make sure the group you are assigned to is selected in the dropdown menu in the forum.
If available, there will be a dropdown menu located at the top of the page, labelled either Visible of Separate groups, select the group that you were in when you made your post.
Another reason you may not be able to view other students' posts may be because the Forum is a Question and Answer forum .
If this is the case, you must first reply to the initial post before being able to view other posts. To reply, enter the thread and click on the reply link located at the bottom right of the post.
After you post, it will be approximately 30 minutes before you are able to see other students' posts.
