Need code, auto change site's language

[Nikola Bosnjak]

I'm using vB 4.0.5 CMS, and site is in 2 languages. I have articles in Croatian and English. I would like vBulletin change the system language depending on what content a user is reading. So, when a user is reading our company info in english, I want "read more..." link in english, but when local user is reading a company info in croatian, I need the same link "read more..." to be in croatian.

So far, I have idea to stick each language to a CMS layout, something like "if layout=1 then langid=1 else langid=2...) but I'm not programmer. I don't know how to do this. Is it possible?

Could I do this with sections, maybe? Becouse all my english content belong to one section, and croatian to another. If I could define default language for a section (I know it's impossible without programming), than my problem is solved.
