The Fight Against Dead End Pages
Dead end pages in the WordPress Codex are articles that do not link to any other pages in the Codex. While this might be appropriate for some pages, we like fighting against our dead ends.
The list is http://codex.wordpress.org/Special:DeadendPages and these pages need to be linked back to categories at the least, or some referencing page to form a navigational loop for the user to follow if necessary.
For example, there are a lot of Function References in the list. Function Reference pages should have a link back to the core Function Reference page. Please copy that link format and paste it onto the bottom of all dead end pages in the Function References.
Pretty easy stuff but very helpful to users trying to find what they need and following the breadcrumbs.
