I've just registered to participate in brand new cgchallenge, and I noticed that there's still no Serbia in country list. It's not a big deal of course, don't get me wrong, just wanted to point it out since Yugoslavia as a country doesn't exist for some time ( there's a whole bunch of new countries made from from ex-Yugoslavian republics). All of them except Serbia and Montenegro are on the list.
So, my suggestion is to correct that when you have time :)
All the best,
