Ok @Andrewds1021 I am on A Christmas Story Wiki. I just adopted it but it is an old wiki from about 12/28/2009. I am looking on my admin dashboard. On there is says advanced options. When I go to that, I see under maintenance reports it says 'Wanted pages'. I click on that and it shows me a list of wanted pages. Under there is shows: MediaWiki:Welcome-message-anon, MediaWiki:Welcome-message-log,
MediaWiki:Welcome-message-user,
MediaWiki:Welcome-user,
and MediaWiki:Welcome-user-page. I wanted to know what these things mean and how to properly make the pages. I only asked for one (IDK why) but now that I have to be more elaborate, I will just ask about all of them.
