I just released the KPAX CMS 1.0 beta (based on web2py).
Create web pages, wikis with locking and versioning, blogs, chats, surveys, video/audio streams. No programming required. Runs off a USB drive too.
The name is temporary.
Lots of a Ajax for user friendly interaction.
Granular Access Control mechanism based on group membership.
Users can create and join groups. Group owner can require approval of memberships applications.
Users can post news and turn them into RSS feeds.
Users can create folders and insert pages in folders.
Users can create surveys and assignments (including anonymous).
Users can create and join chat lines. Chats synchronously and asynchronously, like a discussion board.
Folder pages can be public web pages, public or private wikis, can accept comments, and can contain documents.
Pages have versions and can be compared with previous versions.
Wiki pages have locking so no conflicts.
Documents in pages can be media files. If they are large they are streamed.
Media files are played by the built-in flash player. Movies can be played full-screen.
Assignment are automatically graded and generate reports and statistics.
WYSIWYG editor (similar to but easer than Word)
System errors result in tickets issued to the visitors. All errors/tickets are logged.
