Hi.
I don't know about any accessible courses.
At the moment, I'm doing my best to study Norwegian and Swedish, because I have reasonly got a lot of nice friends there. But those two languages are very much simular to the danish language which is my first language, so for me, it's just a matter of practise.
I hear some iPhone apps for learning new languages are accessible, but I have never tried those, so I don't know for sure. I think the best way to learn a new language is to study some articles and get friends in the country who can explain the basics in the language so you can slowly start to learn it.
Myself, I would find it very challenging to learn people the danish language, mainly because this is a damn strange language, but it's quite difficult to explain how a language is build up when it's your first language, because you really never think about it but just speak it.
The english language is quite easy to learn because it's written as you pronounce the words. But that's only the case in danish, swedish and norwegian and all other languages if you know how the letters are said in the language. I mean, if I write a word in danish, you as a english speaker would think it's pronounced very differently because you might not know how the letters are pronounced in danish. Quite difficult to explain but I think you know what I mean.
I'm very slow to learn a new language and I wish I was much faster to learn. So if you have any tips for that, I would love to hear about it.

Hi Nin.
Cool. Then, you'll also be able to understand the danish language.

Yeah. I think i might learn danish instead only because I already have a course for it. maybe then i can learn swedish by practice. I'm already learning from a friend but it's still very difficult.

Yeah, would be quite interesting!
Reminds me a story a Norwegian guy told me: His schoolmate was from Trondheim and there was some kind of sport event going on and a part of it was long distance running. After this guy had finished, he stood for a while gasping and finally said: "Jeg er klar!"
In standard Norwegian and Danish klar should mean ready, but in Trondheim dialect it means tired.
The same guy told me, that "du er rar" means "you are good looking" in Swedish and if I remember correctly, in Danish as well. Although in Swedish I guess it is spelled differently. But in norwegian it means "you are weird". So if a norwegian says it to a Swede or Dane, both of them are happy. LOL

There should be  a list of this kind of  words comparing Danish and Norwegian somewhere in the wikipedia. As an Estonian, who's native language is similar to Finnish, I really like these  kind of words, which sound similar in similar languages, but have completely different meaning. Linguists call them "false friends".
