WTF/wow. As a native speaker of Croatian I can understand 80% directly and additional 10-15% by "interpolating into the context". Good work. EDIT: I don't like Slovio either, especially because of using x/cx/etc. instead of proper diacritics. EDIT2: I might event invest into learning it. I wouldn't speak any particular "native" language, but could find my way around all Slavic countries.
