As of a recent March 7th, 2019 update, Blackboard Learn's Activity Stream notifications have been broken down into additional categories-- meaning you have even more control over what notifications you would like to see. For full instructions on changing these settings, visit the UNI eLearning Suite FAQ.
Turnitin will take a 5 hour maintenance window on April 20 from 9:00 AM CDT to 2:00 PM CDT. During the downtime, you will not be able to utilize the Turnitin Tool, including Turnitin assignment submissions, processing and grading, in Blackboard Learn.
