z3ext is a CMS framework that builds on top of Zope3. It supports a number of modules out of the box, like eg. a blog. It supports OpenID, caching, jQuery, and a host of other features. It has blogs and forums, content management, site administration including menu tabs and portlet management, intelligent content spaces that contain workspaces (much like Clearspace from Jive Software), project management with milestones and tasks, member and group management, and customizable member profiles. Standard content types include: files, images, documents, news, events, audio, video, and photos. Also included are banner management (top of page, bottom of page, and area below header) with rotating banner content, email notifications, RSS, and a desktop client (Adobe Air Touch).
