Using Blackboard:
Groups
A Blackboard Group enables a group of students to collaborate with each other in a private area (although your Instructor has access to your group). The private group area may include a variety of features including a discussion board, blog, e-mail, file exchange, journals, task list, and wiki. Your instructor will determine the features that are available for your group to use. You may be assigned to a group or provided the opportunity to choose to join a group.
