Module:Anchor
Revision as of 06:14, 20 December 2013 by Module:Anchor>Mr. Stradivarius (Protected Module:Anchor: High-risk Lua module: 20,000 transclusions ([Edit=Allow only template editors and admins] (indefinite) [Move=Allow only template editors and admins] (indefinite)))
 | This Lua module is used on approximately 50,000 pages, so changes to it will be widely noticed. Please test any changes in the module's /sandbox or /testcases subpages. Please consider discussing changes on the talk page before implementing them. |
 | This module is subject to page protection. It is a highly visible module in use by a very large number of pages, or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is protected from editing. |
 | This module is used in system messages. Changes to it can cause immediate changes to the Wikipedia user interface. To avoid large-scale disruption, any changes should first be tested in this module's /sandbox or /testcases subpage, or in your own user space. The tested changes can then be added in one single edit to this module. Please discuss any changes on the talk page before implementing them. |
This module implements {{anchor}}. Please see the template page for documentation.
