  22. * - forum categories and forums can be sorted up or down, locked or made invisible
  23. * - consistent and integrated forum administration
  24. * - forum options: are students allowed to edit their post?
  25. * moderation of posts (approval)
  26. * reply only forums (students cannot create new threads)
  27. * multiple forums per group
  28. * - sticky messages
  29. * - new view option: nested view
  30. * - quoting a message
