The second stage of the "Van Kanighem" tournament.

Can I join too?
And could you explain the rules in more detail (playing one against all AI, etc., and is it mandatory to play as Barbarians?)
I'm basically new here, just registered, and I don't know how things work here.
But I've been on the website several times (downloading files, etc.).
I've played all the games and I like them all in their own way.
