This module can only be edited by administrators because it is transcluded onto one or more cascade-protected pages.

This Lua module is used in system messages, and on approximately 4,800,000 pages, or roughly 8% of all pages. Changes to it can cause immediate changes to the Wikipedia user interface. To avoid major disruption and server load, any changes should be tested in the module's /sandbox or /testcases subpages, or in your own module sandbox. The tested changes can be added to this page in a single edit. Please discuss changes on the talk page before implementing them.
