2016 Winter Tournament: "Frozen Heart"

Regarding unanswered messages in ICQ. There was information that the new ICQ always shows an online status, and all messages go nowhere (when the opponent is actually offline). And it's really unclear - did the opponent read and ignore, or is the opponent simply offline for a long time? Here are 2 options: 1) Opponents in the game write to each other (without waiting for an invitation to play). Maybe they'll connect. 2) Opponents write in the tournament thread and arrange things through the tournament website. And a 3rd option - use the old ICQ. Personally, when I'm offline, the old ICQ also shows me as offline. And messages do get through.
