Hi. I’m quite new to dotnetnuke. I was assigned to create an intranet portal by using dotnetnuke. I’ve created links of all my company’s departments and each links are administered by each department’s admin. However, according to the company’s proposal, once each department admins create and execute their contents in their respective pages, their contents cannot be displayed until they get an approval from the host. Once they’re approved by the host, only then the contents can be displayed. This workflow sounds more like content verification system for me. My big question is, does dotnetnuke have content verification system module? If no, are there any other ways to create such system in dotnetnuke? Any recommended tutorial sites?

You could require that all content be entered in modules that support workflow. Ventrian's News Article and Engage's Publish are two such modules.

Also, DotNetNuke 5.1 Professional Edition has customizable workflow components. As I understand the situation, this is built into the framework.
