Unfortunately you've run into a Drupal bug that we cannot fix. When anyone but an admin creates a new topic, it is not assigned to any forum, and is therefore accessible only to an admin. As of July 2014, it is no longer possible to post to the forums. You can still review existing topics. For support, try the FrameMaker lists.
