I've run into something I need clarification on....
I looked at Sitespinner (per some members of this forum) and it is very easy to use.  On one of the two sites I'm working on, I would like to have people sign in before they can get to certain articles.  I have been told that Sitespinner would not do this but instead I would need to use a CMS (content management system).  
Can I use a CMS to build the entire site or is a CMS using in addition to something like Sitespinner/Dreamweaver etc.?  Mambo and Typo3 are a couple of CMS programs I have found.
Head...starting...to..hurt......
