Discussion forums are centrally located in the Discussion Board tool of your course, but they can be linked to from any course content area. The Discussion Board tool lists every discussion board of a Blackboard course, including those that are specific to groups.
List View: All parent threads that have been created within a forum are presented as stand alone messages. The thread title must be clicked to view the original post and replies within.

Using the Searching Tool
The search function appears at the top of the page throughout the discussion board. The search feature includes a keyword field, date restrictions, and options for where to search.
By default, searches are performed at the current level of view. For example, if you are within a specific forum, your default search will only search threads within that forum. You can select to search in upper levels as well and even search All Forums in Course.
