Sorry I wasn't able to get back to you ASAP. What redirection help do you need? If you mean automatically redirect a page on TechBase to Userbase, not sure that's possible without an Extension.
nothing happens, I see a blank page without any contents and no error messages. Shown URL in the browser is https://techbase.kde.org/Special:MyLanguage/Typographical_Guidelines
So according to me there is a problem with Special:myLanguage when used with redirection.
