We have improoved our site with a help of plugin polyglot, so that it is now possible to post in more then one language. Not everything ist done yet, especialy there are missing translations to particular posts, but the possibility is there yet.
You can see the language switcher in the sidebar. Depending on your choice will be the site presented to you in selected language and you will see each post in this langauge version, unless there is no translation for this particular post.
We will try to write new posts in three languages (slovak, english, german) and older posts translate subsequently too. We would welcome your remarks on phrasing and help with translations.
