[Zope] A product for news

Hi everybody. I am developing a higly customized publishing service without using any CMS. I need to let the administrators of my service (using ZMI) to insert and publish some news that would then be automatically be published in web pages and removed depending on the date. I do know about CMS that offer such a functionality but they also come with whole bunch of things that I don' t need in this context. Can anybody be so kind to point me to a some products that might help me for this. Thanks a lot. Fabio
