Discussion Posts disappear

After publishing a post to the discussion board, the user cannot see his or her post.  This may be due to a filter.  First, be sure you are viewing the forum in List view, rather than Tree view.  While in root directory for the forum, click on the Display button and be sure "Published" is selected.  The other options, for example "Saved", act as filters, so the entire published forum/threads are not shown.
