Curious as to how some of the open source CMS (Content Management System) software products will fit your needs? OpenSourceCMS has a huge list of open source CMS systems (blogs, forums, e-commerce, portals, etc.) that you can test drive.
“The administrator username and password is given for every system and each system is deleted and re-installed every two hours. This allows you to to add and delete content, change the way things look, basically be the admin of any system here without fear of breaking anything.”
It’s great idea which lets you explore whether a system has the functionality or ease-of-use that you want. The best part is even though it’s a test drive, there’s no sales person trying to pressure you into a new CMS that day.
