I don't think you can find many good courses on the internet, you can do a search, but I doubt you find much.
And also, Slovenian is a very complicated language, I think learning it on your own when you don't even know the basics could be extremely hard.
Have you tried to find a course there in your area? If you don't, maybe you can find something at a bookstore, they have language courses on cd, but I definitely suggest taking classes.
Natalija? ... Hm, I wouldn't have believed that if I hadn't see it with my own eyes.
There are also some links in the "resources thread" in the "sticky section" of this forum. I can also send you two or three links if you like. I guess it's not allowed to post them here. There's one site called "e-slovenian" and I've heard that it's one of the best sites for learning Slovenian on the web.
I don't agree Slovenian is a very complicated language.Dutch or scandinavian languages are much worse.I'm Italian born, and in few years I'm grown to simultaneos translation.It has been favourable I studied Latin, and spoke German, there are similarity in cases, in phrase construction. But the best was, I married a Slovenian girl!
As in summer foreigners learn Italian in Perugia, the same is possible in Ljubljana.The best way to learn is of course the full immersion!
