[Zope] Nonprofits using Zope?

We are talking to a nonprofit organization about using Zope for their content management needs. They wanted to know what other nonprofits were using Zope. I searched zope.org and the Zope mailing lists and found only two mentions of nonprofit organizations. I know there must be more people in nonprofits using Zope. Anyone know of nonprofits using Zope? On a related note, I think the "Zope powered links" section of the Zope site should be updated. I think people would be interested to know that cbsnewyork.com and greenpeace.org use Zope.
