Go to the project page and click the Open Questions tab.
You can add open questions to either the beginning, end, or beginning or end of a specific category.
Add a new open question or click a wrench on an existing question.
You can activate and deactivate questions from different sessions. This does not affect the existing response data.
You can also change the order of questions by grabbing them to the left edge with a mouse and dragging.
To remove a question completely, click the Recycle Bin. Deleting the question will also delete all related response data.
