Submittable will save your work as you proceed, but you should also make a practice periodically of scrolling to the very bottom of the application to click the "Save" button. It is a good idea to save your work at the end of each section that you complete.
To return to your saved draft:
- Log in to your Submittable account.
- Click on Submissions.
- Click on the "Saved Drafts" tab.
- Locate your draft submission.
- Click the "Continue" button.
- You'll be taken back to your saved draft, which you can then continue.
