How do I approve/reject submitted entries?
Manual approval from the Applications section, Settings > General > Application process for auto-approval
As the program admin you can approve (or reject) entries from the Entries section. You can use the Set status button to change the status of entries, or use Set rounds to shortlist them directly.
You also have the option to auto-approve submitted entries in Settings > General > Application process. You can also choose to allow making changes and re-submitting of submitted/rejected/approved entries there.
