Category Qualifiers allow you to restrict entries specifically by Project Type, Runtime, Page Count, Project Origin, and Student Projects.
You can even require that submitters input a special password to be eligible to submit to certain categories if you wish.
Category Qualifiers ensure that only relevant and appropriate projects are submitted to your respective categories.
To add Category Qualifiers go to 'My Festival' > 'Edit', then go to Section 4 and 'Advanced Qualifiers' in the details section of any category.
