* 	- 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
