What are your options if you delete an assignment or other element from your Moodle course shell, but later decide that you need it? You may access the Recycle Bin (Administration > Course Administration > Recycle bin) to find a list of the course elements that you have deleted and to restore any needed elements back to your course shell. See detailed instructions on how to use the recycle bin at the Knowledgebase article “Recycle Bin” or at the Moodle Documentation page “Recycle Bin.”
