PFBC is an object-oriented PHP class for building HTML forms. It includes AJAX support, jQuery, reCAPTCHA, TinyMCE, and CKEditor. It features integration with Bootstrap, a front-end framework from Twitter that incorporates responsive CSS (meaning your forms not only look great and behave well in the latest desktop browser, but in tablet and smartphone browsers as well). It supports HTML5 form elements and attributes.
ZedCMS is a simple base content management system from which more complicated systems can be developed. It is designed so a Web developer can quickly produce customised websites, and is not really for users. Users wanting to setup their own websites are better off with a different system, like Wordpress.
