Hi! First of all excuse my english and thanks for helping me, Its a little complicated to me to understand how the script works and how to create my own components, this script its really a new way for me of working, but I know that this would be only in the beginning until I explore more and more.

I wanna create a xml version (as feed rss or xml) of "All notifications" page, "All new messages page" and "All friend requests page", etc, to include in a widget for my website. But im not here to ask you to create this feature for me, I really wanna create it by my own.

But my question is this: If i create a new file.php, what other files I should include in my new php file to make of global elements as: header, body and footer?
