  4. * These files are a complete rework of the forum. The database structure is
  5. * based on phpBB but all the code is rewritten. A lot of new functionalities
  6. * are added:
  7. * - forum categories and forums can be sorted up or down, locked or made invisible
  8. * - consistent and integrated forum administration
  9. * - forum options: are students allowed to edit their post?
  10. * moderation of posts (approval)
  11. * reply only forums (students cannot create new threads)
  12. * multiple forums per group
  13. * - sticky messages
  14. * - new view option: nested view
  15. * - quoting a message
