Submission forwarding occurs during the Challenge. Once your submission has been forwarded to the Seeker, you cannot edit it. Submissions will be forwarded to the Seeker throughout the Challenge, so please be sure to upload only a finished proposal.
Once your submission has been forwarded to the Seeker, you can only submit an updated version of your proposal as a new submission. If you submit an updated version of your proposal, please clearly indicate the new items and/or edits compared to your previous submission. This will allow the Seeker to quickly find the new information and determine how it improves your submission.
