It is used to build and maintain lists of pages—primarily for the sake of the lists themselves. They are not part of the encyclopedia's categorization scheme.
These categories are used to track, build and organize lists of pages needing "attention en masse" (for example, pages using deprecated syntax), or that may need to be edited at someone's earliest convenience.
These categories also serve to aggregate members of several lists or sub-categories into a larger, more efficient list (discriminated by classifications).
Administrators: Please do not delete this category even if it is empty! This category may be empty occasionally or even most of the time.
This is a tracking category for CS1 citations that have parameters without their required pipe.
Citation Style 1 and Citation Style 2 templates report this error when one parameter has text that looks like it is a parameter missing a pipe (|). This error occurs when a template parameter value contains characters and digits followed by an equal sign. If the alphanumeric text immediately preceding the equal sign is a valid CS1|2 parameter name, the module assumes that the template is missing a pipe and emits this error message.
Some legitimate titles will contain a CS1|2 parameter name followed by an equal sign. In that case, enclose the equal sign in nowiki tags, like this: <nowiki>=</nowiki>. For most other cases, simply add the missing pipe.
↑Pages in the Category talk, Draft talk, File talk, Help talk, MediaWiki talk, Module talk, Portal talk, Talk, Template talk, User, User talk, and Wikipedia talk namespaces are not included in the tracking categories. In addition, pages with names matching the patterns '/[Ss]andbox', '/[Tt]estcases', '/[^/]*[Ll]og', and '/[Aa]rchive' are not included in the tracking categories.
