Plugins add function and flexibility to WordPress beyond the built-in features. There are plugins for changing the look of your site, monitoring visitor statistics, adding customized post listings, changing the Administration interface, counting the number of published words within a category, adding images to your site, creating image galleries for photoblogs or bragging, adding meta tags and custom functions, controlling comment spam, adding weather reports, and even hiding your email and web page addresses from harvesters. Plugins expand your use of WordPress, extending the power to control your website's every feature. And if you are creative and useful with PHP, consider creating your own WordPress plugin.
