There are many WordPress users who feel that the default installation for this CMS has very few features and is very limited. They quickly realize how easily this can be expanded when they look at the available plugins. Plugins are basically modules that can be integrated to your WordPress website. They can range from calendars and contact forms, to sliders and animations.
There are new plugins being uploaded all the time and many of them are completely free of charge, with others charging a small fee to get their full features. You will find this option easily inside the WordPress navigation menu.
