[Zope] Newspaper site

Hi all, I'm just wondering if there are any newspaper/magazine sites out there that are using ZOPE for content management and subscriber management. I wouldn't think it would be suitable, but what do you think of using Squishdot for this purpose? Also, is there a list of "powered by" sites on zope.org? I'm doing a site that has both public and private content - hence the need for subscriber-based access. Thanks much Wesley
