|
* 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
