When creating subpages for an existing work, please use the CREATE NEW button right there at the top of the page and pick the page type you want to create from the drop down. It actually makes your work a whole lot easier -- and saves long-suffering admins like me from having to go in and manually fix everything you got wrong -- like a wrong page name entirely (we consolidate all Fridge* entries on a single "Fridge" page). Among other things, it automatically selects and prepopulates the page with the proper Page Template. And if you're creating a page from scratch, please use the ATT Page Creator - It's not hard to find, it's right there in the menu to the left on every page.
Just opening an empty edit window and carelessly slopping new content in all by itself is borderline useless.
