Is there an easy way to reduce clutter in the discussion board area?
Not really. Unlike other areas within Blackboard, there is no way to turn off or hide discussion board forums without deleting them and losing all postings. Clutter and chaos within the discussion board area may be reduced to some extent by planning in advance. Some instructors create a forum for each major unit of the course, some create a forum for each week of the course, some color-code forums, and some rearrange the order of forums so that the live ones are positioned near the top of the screen and old ones are positioned near the bottom.
