Allowing users to create new topics
As of build 18.104.22.168 of the Web Author, you can enable the Create topic function, which allows users to create new topics.
You enable the Create topic function by modifying the templates.xml file in the Content Store. You specify the user roles allowed to create topics as well as the templates associated with each topic type.
Note: In the current release of the Web Author, users can create topics only; they cannot create maps or images.
