This is a threaded discussion tool that can be used through LTI. Multi-level discussions are supported with instructor-controlled hierarchy depth. The instructor can pin, hide, or lock, threads. The tool can be set up to award grades for students when they post a comment on a thread. The tool can be placed many times in a course and each of the placements has its own set of threads and comments. Anonymous students can view the discussions but cannot post to threads. The tool provides usage analytics.
