On the latin wikisource (la.ws) Links to [[Wikisource:Foo]] currently act as interwiki links to en.ws (that is they behave the same as [[:en:Foo]]). This is not desirable. "Wikisource" should be an alias for the local project space "Vicifons" so that [[Wikisource:Foo]] links to [[Vicifons:Foo]], the local name for project space.
The matter has been posted here: http://la.wikisource.org/wiki/Vicifons:Scriptorium#Problems_with_importing_and_with_namespaces but has not generated any on wiki discussion as la.ws is very low participation. I am a local admin.
