Modul:If empty

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