back then I didn't know how to use sessions so I used cookies. You probably didn't see the whole page, only slovenian version. What I did is that I'm setting language depending on the page you are looking. So like moystudio.com/novice is for slovenian language and moystudio.com/news with set cookie to english and so on. Then, I think I'll need to change this, because main page is loaded depending on the cookies, so it's different content for every language, but same url...
if engines don't like cookies, then this explains why my website isn't indexed
about validation, I know, it's a big mess but I'm working on it..
