Summer-Autumn-Winter Tournament for fans of Heroes 4.

Please explain for those who are not in the know: 1. What does this mean:

5-6-7 ZYbr ---
5-6-7 Drakkoska "The Keepers Of The Necromonicon"
5-6-7 Starhan Man is a wolf to man - Homo homini

, i.e., I understand that

We are waiting for you... Just like Drakkoska and Starhan: your game is not finished - your rating will suffer

, but what does ZYbr have to do with it?
2. Are there only seven fans of Heroes 4? (if so, then with me, there will be 8)).
3. How can I play (preferably online, since I only have internet access at work)?
