PNAS Paper Licensing

The PNAS License allows me to provide PNAS-formatted PDFs of papers I author on this website 6 months after publication. Specifically, the PNAS Fees and Licenses Page states the following:

Authors retain the following rights under the PNAS default license:

…

• The right to post the PNAS-formatted PDF of their article on their personal website 6 months after publication, or immediately on publication if the PNAS open access option was chosen. A link to the article in PNAS must be included.

However, the PNAS default license may not provide me the right to give anyone else permission to use the PDF I host. Therefore, the site license does not apply to PNAS paper PDFs.
