To enhance the security of worksheet creation, you can either link worksheet creation to registration or select Only certain users or All Redmenta users in the worksheet settings . In this case, the system will link the creation to that account and students will not be able to enter a different name before completing the form. The name previously registered will appear in the unchangeable line. You can also limit the number of creations, and even minimize it to just one creation. In addition, registered students will have access to all completed worksheets and their results, while unregistered students will not be able to save them, as they will not have an account to log in and check their previous work. Therefore, registration is valuable for students, but not mandatory.
