Are you just wanting to create a website that uses Community Server?
If so, do you already know how to add a domain (or subdomain) and website in DNP? If so, you are 90% done! You could just use the Application Installer in DNP to install the Community Server (2007 is the latest). Once that is done, you're all set. Login to your Community Server website and configure away.
If you're looking for help on how to configure Community Server once it is already installed, you may be better off posting your questions on the Community Server Forum: http://communityserver.org/forums/Default.aspx
Or, you can send me a Private Message and I could help offline.
