Thank you for your continued interest in AdSense.
First of all, I would like to address the main issue of your email - the
fact that only public service ads are showing on your pages.
Unfortunately, we do not provide support for Serbian at this time. Right
now, we are only able to offer language support and ad targeting for the
languages listed at this address:
https://www.google.com/support/adsen...=9727&hl=en_GB.
While we look forward to supporting your language, we do not yet have a
date as to when AdSense will be available to you. If you would like to
stay up-to-date with the languages that we support, please feel free to
check back with us at the link provided above. Thank you for your patience
as we work on expanding our programme.
