Recently a lot of interface messages related to the visual editor's citing system had to be moved. This meant that user guides on mediawiki.org displayed several red links, and had to be fixed manually.
The work in itself isn't difficult, just boring and cumbersome, that is, more worth a bot's time.
I don't think a real process for how to change those messages on translatewiki.net without messing up elsewhere exists.
Raymond helped me understand how he contributes to such a process. The next step would be finding out whether the extension he uses on translatewiki.net would be a good option elsewhere.
Sorry if the tags are random!
