WordPress is an excellent example of an open source Content Management System (CMS). Powered by MySQL and PHP, WordPress is often installed to be used as a blog publishing application. Two of its most popular features are a template system and a plug-in architecture.Â
The first version of WordPress hit the streets on May 27, 2003. It was released by Matt Mullenweg as a fork of b2/cafelog. Mullenwegâs idea took off almost immediately and today a whopping 13 percent of the 1,000,000 largest websites are using WordPress. Within 60 days of version 3.0âs release, it had been downloaded 12.5 million times.Â
The importance of version 3.0 was the merging of WordPress with WordPress Multi-user (WPMU) which allows multiple blogs to exist within a single installation. Administration of the multiple blogs is controlled by a centralized maintainer. This means multiple concurrent copies of WordPress 3.0 may be run from different directories if they are configured to use separate database tables.Â
WPMU adds eight new data tables for each blog. Using WPMU makes it possible for website owners to host their own blogging communities. Webmasters can then moderate and control their blogs from a single dashboard.
