D2L (Brightspace) - Adding Chat to Content
Instructors can add synchronous (real-time) text chat to their courses. The instructor first needs to set up the Chat, then the instructor can put it into the Content section of their course for students to access. UW Colleges Online has created a guide:
D2L describes chat as "an online text-based communication tool. It is a synchronous area where you can talk to your participants in online real-time discussions. From the chat tool, you can communicate with anyone in your course."
