Once your changes are saved, there is a green banner which appears. You should see a button to click which says "Challenges Tracker." Click that button. It should show you one or more options for possible changes, and you should also see a "status" button on the right side of the page. Click any of the status buttons. It will open another page which is called the Suggestion status. You have the option to show how you handled the changes, click any related boxes, and click "update status." That will record your changes for the competition.
