As you may know, this year, CEOI is held in Slovakia (and we've finally got a website that doesn't look like it's from 1990!). There's a list of participants for IOI, but never for CEOI. So let's make it!
Since there are just a few participating countries, I won't bother automating it. Just mention your country's participants in the comments.
UPD: What about other countries? I added Slovakia, but there still aren't many listed.
UPD2: The teams are listed on the official website now.
