What is required from a judge for the PSA submission?

A judge's signature for approval is required for the PSA submission because it signifies that the submission has been reviewed and meets the established guidelines and standards set forth by the competition. This signature serves as formal approval, confirming that the judges have assessed the PSA and found it to be compliant with the rules, which is essential for the integrity of the competition's evaluation process. This step is crucial, as it ensures that only those submissions that have been properly vetted are accepted for consideration, thereby maintaining the quality and credibility of the event.
