Learning resources in draft status are hidden by default. It should be possible to make draft content visible for other users to have collaborative authoring. Checkbox "Draft version is hidden from other users" is displayed for the first author in the About-page for learning resources (web pages, presentations, exercises, PILOT's). This checkbox is checked by default.
See the UI prototype: http://lemill.org/trac/attachment/ticket/1726/editing_settings.png
