Sort forum list and showing only specific forums
I run a Drupal 7 forum. The forum structure is built by the users itself by creating tags. In the forum list, all forums are listed. I see there also subforums which make no real sense. For example, the subforum Modules of Drupal 7 makes no sense as a standalone forum. It makes only sense in combination with the main forum Drupal 7. How can I hide the subforums in the forum list?
