Does Craft Have Publishing Workflow? Is it possible to allow some users to write content &amp; an editor can edit &amp; publish / approve it?
You can give a user or a user group the following permissions (on each section separately):


Edit entries

Create entries
Publish live changes
Delete entries
Edit other authors’ entries
Edit other authors’ drafts



If a user only can "create entries", but not "publish live changes", then he is not able to publish an entry (but he can create the entry).
