You accidentally posted in the section "for learning English." I don't know anything about Swedish, but be aware that italki does not actually have language learning tools as part of the website itself. It is really a website for connecting learners to teachers who give personal, face-to-face lessons over the Internet using videocalls over services like Skype. It also manages the payments.
If you want individual face-to-face lessons from an individual human instructor, your first step is to explore the "Professional lessions" section.
Italki is also one of a number of websites that help students connect with "language companions" who are interested in practicing conversation over the Internet. As you can see it also has (limited) text-based forum-like tools, but these are not really something you can use to learn a language.
