PostNuke is CMS that creates an impressive, dynamic web site and provides the webmaster with a site they can administer with a minimal amount of HTML knowledge through a web browser. PostNuke can do anything from traditional blog websites, to a community members' only website with hundreds of users. PostNuke can scale to thousands of uses but is just as easy to create a small website for friends and family. It has a strong user community providing many third party modules/themes to further extend the core features.
