Once a Thread has been made, Instructors and students have a number of ways to reply / interact with the thread that can facilitate discussion, collaboration, and communication.

Hearts, Stars, and Watch

  1. In a thread, instructors and students can click the "Heart" icon to the left of the comment / thread they find useful.
  2. Likewise, they can click the "Star" icon in the top-right on the threads they want to refer to later.

The number of Hearts that a post receives is viewable by the entire class, but the Star is private to the individual.

    1. Not Watching - users will be notified of direct replies only
    2. Watching - users will receive notifications about all activities
    3. Ignoring - users will never be notified

Pinning Threads

Only Instructors can "Pin" a Thread. Pinning a thread keeps the thread at the top of the Category's thread list.

  2. Instructors can also "Accept" a comment to mark the question as resolved.

Removing Duplicate Threads

If a new thread is created that duplicates the discussion or question in another thread, you can consolidate the threads.

  1. Click the three dots on a thread and select "Mark as Duplicate."
  1. A new window will pop up where you can select which Thread this is a duplicate of, and then confirm by clicking the "Mark as Duplicate" button in the new window.
