NOT wordpress, joomla, drupal...
I need (free) content management for a website. I need to allow content creators to modify pages in sections, not whole pages.
Imagine a web page that has 3 columns, and each column's content is handled by a different person. None of them know HTML or CSS, and must not be able to get to that background code (because they will break the page, every time.) They must only get access to modify their one section of content.
Does any free CMS software spring to mind? I can't find one like that - they are all set up to edit the content of the whole page.
Bonus points: if the CMS already uses CKEditor as a richtext editor. If not, then I will need to change the code of the CMS so that it CAN use CKEditor.
I can write this from scratch (using php, mySQL, and CKEditor). but I don't want to. There must be something like this already written, to save me the time.
