Module:Sanctions/sandbox

Module documentation[view] [edit] [history] [purge]

This module provides utility for the community sanctions system. It should be called using one of its wrapper templates (eg {{Gs/talk notice}}).

To add, remove or modify sanctions, you only need to edit Module:Sanctions/data with your changes. Be careful when saving changes; syntax errors on /data will cause every transclusion of any GS template to show an ugly red error message.

The above documentation is transcluded from Module:Sanctions/doc. (edit | history)
Editors can experiment in this module's sandbox (edit | diff) and testcases (create) pages.
Add categories to the /doc subpage. Subpages of this module.
