Zikula
PostNuke

Zikula follows an active development cycle aiming toward frequent releases.

Development of the program began as a successor to the PostNuke framework, and as of 2008 replaced it as the focus of all new development.

LimeSurvey has also been ported by third parties to various content management systems, such as PostNuke, and XOOPS.

AutoTheme was born out of posts in the PostNuke forums from users that were frustrated with modifying their PostNuke sites and themes.

At that time, all themes were written in PHP and required a knowledge not only of PHP, but of PostNuke, its functions, API and interworkings.
