The Chat activity allows course members to hold real-time, text-based conversations with other course members. Different chat rooms can be set up for the same course. For example, a course may have multiple Chats, some where meeting times are scheduled, and others that are always available. Chat sessions can also be logged for reference, with instructor control over who can see the logs.
Instructors (and students, if the instructor allows) can view logs of previous sessions in a Chat activity. Instructors can also download individual sessions or export all sessions from a chat at once, and delete logs.
