RE: [Zope] Web-Based Educational Systems using Zope?

Hi. Has anyone built a web-based educational system (tracking assignments and grades, distributing lecture notes, etc.) using Zope? If so, I'd be grateful for a pointer.

I'm sure there are projects in various states all over. Someone recently posted a solicitation for people to help him develop something just like this. I, for one, think a project like this would be awesome... --Rob
