Description: Siteframe is a community content management system written in PHP4 and MySQL. It separates presentation from content by means of a template/macro system, and supports online user registration/validation and online editing of content. There is extensive support for images built-in (automatic thumbnails and resizing), and is often used for image libraries and photography interest groups. The online document structure is extensible and very flexible. Release 3.1 adds "subscriptions," the ability for users to request notification on system events such as comments on a document.
