Translation troubles

Lately, I have been working hard to make the site bilingual. I want at least the most important pages to be available in Swedish as well as in English. In situations like that, Drupal sometimes appears be a bit difficult to see through. There is a lot of information available, but not exactly the one you need. However, yesterday I found the instructions I needed, and now the work has begun to make translation and to allow the easy switch between English and Swedish. It is not easy, and new problems appear on the way, but there is hope.
