Best Free CMS For Portfolio, Studio, Company, Business Website Or Your Blog

I've used several CMS (content management system), for my blog or my website, since 2006 until 2011. And all that I use, very easy to understand, use, and operated. And also supported by a forum that provides a lot of help or guidance. Here is the CMS I have ever used:
  1. Indexhibit: Indexhibit is a web application used to build and maintain an archetypal, invisible website format that combines text, image, movie and sound. Site: indexhibit.org
