Some may see PN as a weblog or content management system. But PN is
more than that, PostNuke is a community, content, collaborative
management system, a C3MS. It's your electronic toolbox, a set of tools
allowing you to build a dynamically generated web site that five years
ago would have cost thousands of dollars to launch.
PN is unique because it not only provides you with a wonderful set of
tools, but it provides you with a community of users. PN is a community
that responds to you when you need help or information.
