WordPress is Expandable

The other really cool thing about WordPress is that there are thousands, literally not an exaggeration, of developers around the world that work on WordPress. So if there's something you want it to do the odds are there's a plugin that's been created that you can add to your website and it will do exactly what it is that you are needing. Like Caroline was saying, you can add a booking plugin or you can add a membership plugin or you can add a certain contact form that's going to take payment through PayPal or whatever it is. There's something out there that's most likely already created
and you don't have to recreate the wheel. That is a huge advantage of WordPress.
