I appreciate the work you're doing to fix links on pages. But can I ask you to keep pages to using hyperlinks (example: [[Ranch House|ranch house]]) rather than full URL linking (example: [http://slimerancher.wikia.com/wiki/Ranch_House Ranch House]).
Articles check for page names via hyperlinking so the only time URL linking is necessary is for another website, such as wikipedia.
Broken links appear as red so its not hard to identify. Click on that broken link then type the page/article you want to link to the page you are editing.
For Example: The link appears red because the text on that box is written as "the ranch" instead of "The Ranch". It cannot identify "the ranch" due to capitalization. You may put hyperlinks but they are rather lengthy when you do it in Source Mode, but you did copy paste.
Some links that you editted were already fine such as "Spiral Stream" on the Slime Science Resources page. You edited it because you thought that the link was broken. Hovering your mouse on to a link will tell you if "This page does not exist". If that text doesnt show up then the link works fine.
There are some cases where the page says "Redirected from: Previous Name of a Page". Take the Far, Far Range as an example. If you type The World as the link, it will direct you to the Far, Far Range because The World was renamed to Far, Far Range. Attempting to visit the Redirect Page will only show an Arrow with the link of the page's new name.
