I tried to redirect the page but then I reverted it (https://techbase.kde.org/index.php?title=Policies&diff=100281&oldid=100280) - the page is this special link https://techbase.kde.org/Special:MyLanguage/Policies and I'm not sure how to change that.
I'm open to helping out with this task, but not sure how altho I know a fair bit about the tool from Wikipedia.
Thought maybe the sidebar was a template (browsed https://techbase.kde.org/Special:Categories) but I don't see it.
Happy to help if someone can point me in the right direction.
