This is the documentation page for Module:User error
It contains usage information, categories, and other content that is not part of the original module page.
This module is neither invoked by a template nor required/loaded by another module. If this is in error, make sure to add
{{Documentation}}/{{No documentation}} to the calling template's or parent's module documentation.
A less intimidating version of the built-in error(...) function, to help editors fix their mistakes when transcluding a template.
