The Knowledge Center
The Knowledge Center is a one-stop-shop where learners can access everything they need to get the most out of their training.
They can find course reference materials, upload and download assignments in the file sharing area, discuss course topics in the forums, use the notepad while studying, contact their instructor or other members in their learning group, and much more.
It is highly configurable; you may turn on and off tabs so that the center contains only items that are relevant to the course.
