This issue has been resolved. Please contact firstname.lastname@example.org if you continue to have problems accessing Bb as a guest.
Problem: When entering a course as a guest (non-authenticated user), users are redirected to the login page or see an error message.
Solution: Some browsers have been reported to work better than others when accessing a course using guest access. While we await a solution from Blackboard, it is recommended that users attempt to enter the course using Internet Explorer or Firefox.
