The assignment activity - one or two submissions to submit.

A brief post.  I recall numerous times in the past year, students getting confused by the assignment activity behavior.  By default, when an assignment file is uploaded, it is not completly uploaded yet.  What I mean is the default behavior looks like this after uploading a file to an assignment.

The assignment is not uploaded yet.  There is another step, since there is also an option to edit the file just uploaded.  Make sure the student clicks the Submit assignment button, again.

To change this behavior, edit the activity from the course page and change the option to no feedback.  Then, when the student uploaded the file, that's it.    No need to submit again, and no option to upload again.

Now, when I click Submit assignment - I get a final warning from moodle.
