I agree that you could just create a Resource and place your hyperlinks to other courses/discussion within it.
For users who know HTML and are happy to copy and paste URLs to create these links that is fine.
I am thinking about a way to streamline the creation of hyperlinks to other components of the site such as Courses/Topics/Discussion Forums etc. Rather than copy and paste URLs you would be able to select the Course/Topic/Discussion from the selector list.
