[Zope] restricted access to ZClass instances

Hi everyone, A student and I are working on a ZClass for displaying school news on our school district Web site. There will be a number of categories such as sports, academics, arts, etc. We plan to have someone in charge of submitting news item for each category. We'd also like to arrange it so that whoever is responsible for sports (for example), can only add sports news. What would be the most efficient, logical, and aesthetically pleasing way to do this? :-) -Tim -- Timothy Wilson | "The faster you | Check out: Henry Sibley H.S. | go, the shorter | http://slashdot.org/ W.
