I don't quite get the part
* A stand-alone link, such as the application-names in Applications/Internet, should use the form [[Special:myLanguage/Ark|<translate>Ark</translate>]]
What does "stand-alone link" mean? I'm a little bit concerned about this - how many link need this special treatment?
It means exactly what it says - a link that stands alone in a section such as the application names in Application/Internet. How many? Ideally every link in that situation. The rules we are formulating come from the needs of the translators.
So it doesn't apply to a link like this for example?
