Do you want us to add Exponent to the Bitnami library? You can vote for it on our wishlist.
Exponent is a website content management system that allows site owners to easily create and manage dynamic websites without having to directly code web pages or manage site navigation. It provides an intuitive and flexible content editing system that allows website pages to be edited on the page as it is displayed (visit the page and make the change). No additional applications need to be downloaded by a user to permit them to use Exponent. Everything, from user management, site configuration, and content editing (and content approval for large, multi-administrative sites) is done within the system.
