While the interface to Turnitin has changed, the status of the plagiarism detection software's use at UMBC remains unchanged.
As announced last spring, there remain unresolved issues with Turnitn possibly "crashing" inside Blackboard versions 7.2 or higher (which UMBC runs).
While there were minimal reports of this happening at UMBC, the Division of Information Technology (DoIT) still wants faculty to be aware of these potential issues as well as other alternatives (e.g., using Turnitin oustide of Blackboard or using SafeAssign, which is Blackboard's plagiarism detection tool).
In the meantime, DoIT will continue to support both Turnitin and SafeAssign for the Fall 2008 semester, but faculty should weigh their own concerns about interruptions in deciding which tool they should use.
FYI: Once you use the new Turnitin interface, there is a "switch back" option to return to the original interface.
