[Zope] zope objects question

Hi! in first place i want to know if there is some tutorial that explains how the zope objects are stored and how to manipulated them! The second question is about some work i have to do: I am going to have different portals, but they have to share news and some other modules for example if i publish some news in one portal the same news have to appear in the other portals. thanks SMS GRÁTIS do seu PC para qualquer rede nacional (TMN, Vodafone, Optimus e PTC).
