Note: You only need to accept this once on a specific Moodle server. Once you have accepted the End User License Agreement for Turnitin on the current Moodle server, you will not be prompted to do so again. (If you have already accepted the agreement, but Turnitin still says you haven't, download your submitted file, delete the current submission, and reload. This usually resolves the issue.)
Appearance and acceptance of the Agreement
The agreement will appear in a popup, whether or not your browser disables them, after selecting the button shown below.
On a new paper submission, you will see the following:
After selecting the big blue button, click I agree -- continue in the new window that appears.
As with all user agreements, we recommend copying the agreement and emailing it to yourself to maintain a copy in your records.
