Discussion and Journaling
Blackboard provides discussion boards for courses, which are accessible through the discussion link.
There is also a on Livejournal community for you to post your weekly journal entries about your experiences with the Web. To join the community, first create a free livejournal account. Visit the user info link on the main page of the community journal. There, you can click on links to add the community as one of your 'watched' sites and also join the community, in order to receive posting access.
