Hi Jona,
welcome to the mailing list for the MediaWiki software.
If you think that content on a website (e.g. Wikipedia) is wrong, then
please bring this up on that website (e.g. the related Talk page).
If you think that the MediaWiki software itself on that website does
something wrong, then please follow

Thanks a lot!,
