WordPress is a powerful personal publishing platform, and it comes with a great set of features designed to make your experience as a publisher on the Internet as easy, pleasant and appealing as possible. We are proud to offer you a freely distributed, standards-compliant, fast, light and free personal publishing platform, with sensible default settings and features, and an extremely customizable core.

More simply, WordPress is what you use when you want to work with your blogging software, not fight it. WordPress is publishing software with a focus on ease of use, speed and a great user experience. WordPress is blessed with an active community, which is the heart of open source software. It has the following excellent main features.

Locally Installed

WordPress is designed to be installed on your own web server, or shared hosting account, which gives you complete control over the weblog. Unlike third-party hosted services, you can be sure of being able to access and modify everything related to your weblog, in case you need to. This also means that you can install WordPress on your desktop or home computer, or even on an Intranet.

User management

WordPress uses user-levels to control user-access to different features, so you can restrict the ability of individual users to create or modify content in your weblog, by changing their user-level.

Dynamic page generation

No rebuilding of all your pages each time you update your weblog, or any aspect of it. All pages are generated using the database and the templates each time a page from your weblog is requested by a viewer. This means that updating your weblog, or its design is as fast as possible, and required server storage space usage is minimal.

Template Driven Design

WordPress uses templates to generate the pages dynamically. You can control the presentation of content by editing the templates using the Template Editor tool and the Template Tags.

Moderation

For the control freak in all of us, WordPress provides an array of moderation options. You can moderate

• all comments before they appear on the blog
• comments with specific words in them
• comments posted from specific IP addresses
• comments containing more than some specified number of links.

All these moderation options keep spammers and vandals in check.
