Let's say I'm making a site in EE and I want to specify a URL on a specific page. As a former wordpress dev, I did that with ease, how would I do that with EE?
You can also use the Template Routes system. This gives you extraordinary control over what templates are used to generate content in response to URL entries. Hugely powerful, but with quite a steep learning curve. If you are happy to buy an add on there is also Structure which overlays a Wordpress like environment over EE.
