(I don't know if this question is appropriate here. I'm going to take a chance.)
If you're writing a paper according to the APA (American Psychology Association) standard and you need more than five levels of headings, what is the appropriate way to solve this?
According to the APA manual (Sixth Edition, page 63), there are five levels of headings that you can use. However, there is nothing mentioned about what to do if you need more than this.
