How do you make edit notices on your own wiki?
Topic on Project:Support desk
You mean?
The thing what appears when you go to:
Ah, ok. For this, i think the best is to read this page: Help:Edit_notice. If you have questions then, please ask :)
Is it possible to allow users to create edit notices without giving them the editinterface permission?
I think no :) (because this is the use case of "editinterface" permission, to avoid "Normal" users to change the interface messages ;)).
How does Wikipedia do it?
The edit notice for my wikipedia page: https://en.wikipedia.org/wiki/User_talk:Cregavitch/Editnotice
The edit notice being displayed: https://en.wikipedia.org/w/index.php?title=User_talk:Cregavitch&action=edit
