So, it looks like you need to split a page. Well, there's two ways to do it, and you'll need to pick one. Soft splitting is done by making a line break between the things that would be on the page, most commonly work subpages like YMMV and WMG, as long as the pages are relatively small. Hard splitting is when a page has all the content moved to a different set of pages and then the original is turned into a disambiguation or index. This is preferred for works and large pages.
