@Matiia: Anyone can improve the translation at https://translatewiki.net/w/i.php?title=Wikimedia:Portals-wikiversity.slogan/it&action=edit
This does not need a ticket in Phabricator, in my humble opinion?
@Matiia Thanks for pointing out this issue. We'd love to have you help out with translating the page on translatewiki! Given @Aklapper's comment above that this can easily be changed on-wiki, pointing directly to the relevant message, I think this task can be marked as invalid since it's not really an issue for tracking in Phabricator.
