Hi,
Many thanks for the beers!
There is currently a process by which approval based publishing can occur, where authors create content in private areas not visible to the public and more priveledged users can publish the content to visible pages, its described on the bottom of the Roles and Permissions page.
I do see this approach as a bit of a workaround and a more formal workflow system is planned for on our road map. There is actually a community member working on pieces of this puzzle now, but I do not have a timeframe when to expect to see it as of yet.
Best,
Joe
