Textpattern - A free, flexible, elegant, easy-to-use content management system for all kinds of websites, even weblogs. Built into Textpattern is Textile, a simple syntax for nudging plain text into structurally sound and stylistically rich web content. Ordinarily fussy text amendments such as headers, hyperlinks, image tags and tables are created with one or two simple markers. Compared to navigating the tag soup of markup, writing and revising with Textile is much more intuitive, being closer to working with ordinary text. Once you’re ready to publish, copy marked up with Textile is automatically converted to valid XHTML, and because Textpattern stores both versions of each article, revising and updating is a snap. When composing or readying articles for publication in Textpattern, you can switch between three views of the article:plain text, XHTML (the code with which a web browser renders the article), and a rendered preview. Sites published with Textpattern can employ unlimited registered contributors, each of whom may be assigned privileges by the publisher of the site. Five levels of privileges (publisher, managing editor, copy editor, writer and designer) are provided, and each reflects different access to article creation, approval, editing and deletion, and to image uploads, page design and CSS, and of course adding more contributors. Installing and managing plugins that extend Textpattern's abilities is straightforward. Once installed, plugins can be turned on and off from within the Textpattern interface, where detailed help and access to parameters used by plugins is also available.

Now just over two years in the making, version 1.0.0 is an immensely stable, thoroughly tested, and well-written piece of internet software ready for any webserver, running on PHP versions as low as 4.0.0 and MySQL versions as low as 3.22. The board was founded as a development project aimed at experimenting with the limitations and uses of the PHP language by Jason Warner and Mark Elliot. Over the past two years it has undergone, minimally, three major rewrites, numerous full database restructures, and several changes. The last year of development is clearly visible in an online CVS repository, and the software has been, and remains to be for all future development, open source, and free for you to use. The success of the board speed wise comes from constant optimization of code. The base structure of the application has been in place for almost six months now and has remained relatively unchanged. Several modules plug-in to the software, making it both extensible, and easy to figure out. The limits of PHP's OOP protocols has been tested with our software, and an even mixture of both Jason's and Mark's code-theory has been authored into the methodology of how the software works. Admittedly, the software is not OOP in the 'true' sense of the theory, but uses several advantages of objects to facilitate an easy modified working base model. The board is easy to modify, as shown by several users even in the Beta stages of the product.
