Yes, courses can be hidden on Moodle. This can be done by the course instructor or administrator by changing the course visibility settings. When a course is hidden, it will not be visible to students in their course lists, but instructors and administrators can still access and manage the course. This feature allows instructors to prepare and organize their courses before making them visible to students. **

There could be several reasons why you are unable to log in to Moodle. It could be due to entering incorrect login credentials, such as username or password. Another possibility is that there may be a technical issue with the Moodle platform itself, causing login difficulties. It is also possible that your account may have been deactivated or suspended for some reason. I recommend double-checking your login information, trying to reset your password, and contacting your institution's IT support for further assistance if the issue persists. **

To activate notifications on Moodle, you need to go to your profile settings. Click on your profile picture in the top right corner, then select "Preferences" from the dropdown menu.

You can choose to receive notifications for various activities such as forum posts, assignment submissions, and messages. Once you have set your preferences, make sure to save the changes to activate notifications on Moodle. **

No, teachers cannot see deleted submissions on Moodle. Once a student deletes a submission, it is permanently removed from the system and cannot be retrieved by the teacher. Teachers can only view submissions that are still available in the system. **

No, teachers cannot read your private messages on Moodle. The messaging system on Moodle is designed to be private and secure, and only the sender and the intended recipient can access the messages. Teachers do not have the ability to read private messages between students or between students and other users on the platform. It is important to remember, however, that all communication on Moodle should be respectful and appropriate for an educational setting. **

No, as an AI language model, I do not have the ability to interact with Moodle or any other external platforms. However, typically on Moodle, users may not have the option to enlarge profile pictures as it depends on the settings and features enabled by the administrator of the Moodle platform. If you are looking to enlarge profile pictures on Moodle, you may need to check with your institution or the administrator of your Moodle platform for assistance. **

To unsubscribe from a Moodle course, you can go to the course page and look for the "Unenroll me from [Course Name]" link in the Administration block on the left-hand side of the page. Click on this link and confirm that you want to unenroll from the course. Once you have confirmed, you will be unsubscribed from the course and will no longer have access to its content. **

The size limit for uploading files on Moodle may vary depending on the settings of the specific Moodle site. If the file you are trying to upload exceeds the size limit set by the site administrator, then yes, it would be considered too large to upload. In this case, you may need to either reduce the file size or consider alternative methods of sharing the file, such as using a file-sharing service or breaking the file into smaller parts for upload. **
