New players will first need to click on "join the community", which is free. You will receive an email that you've successfully joined the community, then you will be able to register for the league.
The Jamboree is for players who want to play in the league but have not done so in the past. It allows us to see new players play and helps us properly place them, by ability, in the league. New players should be prepared to play for about an hour.
