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