Scholar Ultra Courses has two methods of incorporating Discussions. The first is to create individual Discussion spaces, which can then be incorporated into the Course Content feed, while the second is to use the dedicated Discussions space provided by each Ultra Course.
Creating Discussions In Course Content Feed
Scroll to the Participation and Engagement section, and select Discussion.
You’ll be taken to the New Discussion screen for the Discussion you created. Give the forum a name, and a description for what the Discussion in question will be about.
This space will also allow you to alter the settings for this specific discussion. To open the settings, click the gear icon on the upper right hand side of the screen.
This will open up the full list of settings for a Discussion. This includes whether the discussion is visible in the Course Content feed, whether the activity in the discussion is visible before any given student posts to it, whether students will be able to edit or delete the posts they make to a discussion, and whether participation in a discussion will generate a grade for students. From here, you can also assign a discussion to a specific group, if you have already created student groups. (Will link to Groups once that article is complete)
Selecting the option to grade participation in the Discussion will make additional options appear, such as due dates and point values for participation in the discussion. The ability to grade participation using a rubric will also be available at this point.
To save your settings, click "Save" at the bottom of the settings list. The discussion will be set to the Course Content Feed and ready to accept responses from students.
Creating Discussions in Dedicated Discussion Space
The link to the Discussion space is shown on the top bar of each Ultra course. 
At the top of the space, you will see two buttons: New Folder, and New Discussion, as well as a gear icon. 
New Discussion will allow you to create a new Discussion directly inside the space, with identical tools to those seen in the Course Content section. New Folder will allow you to create organizational folders, which can be used to sort discussions by category. Discussions can then be created inside folders. 
Finally, the gear Icon will open Discussion settings, which primarily consists of whether students are allowed to create discussion topics themselves.
