Adding a custom page while keeping the sign-in state?[Metro]

[jpwanabe]

I know how to make a webpage that would be independent of the forums itself, but how would I make a page that has the header and footer of a normal page but has a body of what I want?

Where it says my custom stuff is where I want to edit but be on it's own page and not a quick edit using f12.

Does the middle content need to be dynamic? I only see an easy way which allows html/css/js. And -- what is f12 ?
