How does someone access a course via guest access?
Point a browser to http://suze.ucs.louisiana.edu/moodle/ and click on one of the Course categories. Then scroll through the course listings, selecting one. This results in a Login page; choose Login as a guest near the bottom of the page. You will then be taken to the previously-selected course (unless it denied guest access). If you would like to create a link to your course page for convenient guest (that is, public) access, login to your course as guest as described in the previous paragraph, and note the URL used. In particular, note the id= value. Then use this URL for automatic guest access to that course: http://suze.ucs.louisiana.edu/moodle/course/view.php?id=N&username=guest (but substitute the actual id number for N).
