The Announcements Forum is a special forum for announcements that is automatically created when a course is created. A course can have only one Announcements Forum. Only teachers and administrators can post in the Announcements Forum. The Announcements Forum is equivalent to Announcements in Blackboard.
One-on-One Forums enable instructors to provide interaction and assistance to individual students within a specific online course. Instructors create these forums.
Instructors and students have several options while viewing a forum.
Logged in users (students, teachers or administrators) may send messages to each other regardless of whether they are enrolled in the same course.
Messages are sent via a popup Message window.
The Chat activity provides a synchronous (real-time) discussion.
