I'm using the Tarski theme on my blog to test WordPress.com and I've noticed that not all of the theme is translated into Swedish. Some examples: the page "Home" (should read "Hem"), "Subscribe to feed" ("Prenumerera på RSS-kanal") and the word "in" in the statements regarding when a post was made (like "2 maj, 2010 IN category X" when it should read "2 maj, 2010 i". When I go to comment a post there are even more mix ups of English and Swedish.
I've gone through all the settings in the Dashboard but I can't seem to correct this. Is it possible?
The blog I need help with is vladnetchka.wordpress.com.
