BitNami ocPortal Stack for Linux (64-bit) is a CMS with many Web 2.0 features for sophisticated sites. ocPortal supports many types of content and integrating rich media and advertising into them. Community features include forums, member blogs, chat rooms, WIKI, and content commenting or rating. ocPortal lets you decide exactly how your site will look and behave. Features are plentiful, well integrated, and optional. Out-of-the-box your site will meet the highest accessibility and professional standards. BitNami Stacks are completely self-contained, and therefore do not interfere with any software already installed on your system. By the time you click the 'finish' button on the installer, the whole stack will be integrated, configured and ready to go. BitNami Stacks can be installed in any directory. This allows you to have multiple instances of the same stack, without them interfering with each other.
