/**
* 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.
