I did an extension SkinCustomiser made for helping to customise wikis, specially in wiki farm environment. It can add customised messages, for example for the sidebar (see here). So fine, so well. But I also like to override some core-messages, for example in the login Special page. It does not work. Is there any way to do that?--WikiForMen (talk) 14:57, 22 October 2022 (UTC)
