Hi, to your problem: Probably take a look here: https://github.com/TheSandDoctor/misc-code-bits/blob/master/LoginSignupSpec… That might be related to your problem. However, not sure what you actually want to achieve, and if you're just doing it out of fun or if you want to use it in production. If the latter one: Don't do it. Changing the code of mediawiki/core or any extension is basically the worst thing you can do. You will lock out yourself from being able to easily upgrade your wiki and you never know if you probably break crucial features or security barriers with changing the code. Instead, you should try to do whatever you want to do by using one of the several hooks, MediaWiki provides, to customize the software, This makes sure, that you're using well-defined and supported interfaces to actually change the behavior of your wiki. In your case, the AuthChangeFormFields hook, might be out of interes.

I have found the code responsible for the form, but for some reason the checkbox does not show up. As a test, I then went and tried copying and pasting one of the existing text boxes (with its IDs etc changed of course) to see if that would work. Nothing shows up other than the fields already present. Does anyone have any ideas what could be blocking it and/or what I am missing? Below is the diff of the change that doesn’t show. https://github.com/TheSandDoctor/misc-code-bits/commit/4f2f6221c64095777622… Thanks!
