Discussion of CIS-2015 details

Alexxl and Albert@s, listen, can we bring some friends? They don't really play Heroes, but they can go fishing, hunting, play billiards, chess, and almost anything else. They can even play poker. They're all good, decent, and fun guys! I showed them "Olympia," and they wouldn't mind spending the May holidays in such conditions and with such company. Or is the gathering limited only to Heroes players?
