Websites in Slovenia and Estonia are just now getting access to AdSense. Sites in these countries can now earn money through Google’s popular publisher program, which enables sites to show ads from Google’s network.
Google announced as much in a post on its Inside AdSense blog, where product sales lead Ulrike Jung tells publishers:
If your application for AdSense with a Slovenian or Estonian website was previously disapproved for being in an unsupported language, you’re welcome to resubmit it by logging in with the original login details you provided.
For now, you’ll be able to access the interface and help resources in English, as we heard from your feedback that you’d prefer to begin using the program in the meantime. Rest assured that we’re working to provide help content in these languages in the near future.
We’ve just added Estonian and Slovenian to our list of supported AdSense languages (http://goo.gl/cLsQm). If you manage sites in Estonian or Slovenian and already have an AdSense account, simply place new ad units on your policy-compliant pages to start earning. We’re working to continue expanding our program to more languages, so stay tuned!

For those new to the AdSense program, you might find some useful resources in Google’s AdSense Help center, where it offers a code implementation guide and an optimization lab.
