This is the site http://davidhornbrook.com/wordpress/sample-page/
All I want to do is change it so that it does not say sample-page. I want to change it to something else. Same with this page http://davidhornbrook.com/wordpress/2012/04/20/hello-world/
Any and all help would be appreciated as I am new at this. I have researched the forums but all the stuff I found was 1 year old.
