Check your "Official Course Enrolments" page:
Your official course enrolments will be listed (with links to the course site, if available).
If you've changed courses or sections recently, you'll see the change in OWL within 24 hours.
Course sites can be set up for the Winter term and some of the Spring/Summer terms. Start by going to Worksite Setup and then "New". If you do not see a section that you are teaching, please confirm with your department that you are the "approved instructor for the correct term".
