How do I add new people to an existing Conversation?
Canvas recently introduced a new page design called the New Canvas User Interface (UI). This lesson may include two images for specific steps to show the difference between the two designs. Unless otherwise indicated, the functionality and location of the components remain the same. The view available to you is determined by your institution.
You can add people to an existing thread in the Conversations Inbox.
Note: When adding users to an existing conversation, you cannot change the course or the subject line.
Start to type a name in the the text field , or click the Address Book icon  to filter by users or course groups.
