.communities is an AJAX-enabled, multi-user content management system that allows for an individual or an ISP to quickly create and administer a collaborative website such as a club site, a user group site, or a news site. Based on the popular source code of the original Community Starter Kit (CSK) released in 2003, it has a number of standard content modules and supports multiple site/url configurations via a single database. .communities contains all the features that you would expect to find in any other Web 2.0 application; HTML content, Wikis, Blogs, Discussions, Photo Galleries, RSS Newsfeeds etc. as well as a plethora of advanced configuration options and settings. Out of the box, .communities has everything you need to create and manage most types of site - its easy to use and runs on a core framework that can be fully customised if required.
