I'd like to customize the welcome message in the Civilization wiki again. Currently it looks like this. I read Help:Welcome tool where it says the welcome message should be located at MediaWiki:Welcome-message-wall-user but that's clearly not it. How do I customize the welcome message? Especially the part with "If there are no active admins here" bothers me a lot, as we are a very active wiki.
