are a way of having forums within another forum. A group of related topics can be made into Subforums and put within a non-posting Parent forum that can contain them. The Parent forum shows on the main board page. Using the Soft Style of Subforums you can see the Subforums's names in the Parent Forum's description and when new posts are made in the Subforums their names will go Italic. When there are no new posts the names are regular fonts.
