It is still in test mode, and the only way to get on is to get an invite from someone else that is already there!
If you want to get on early, I have a couple of invites to give out. (sorry - they randomly give a few to some of the current test users).
If you want an invite, I need your first & last name, plus your current e-mail address where the invite will be sent. NOTE: HOTMAIL automaticly deletes the Google invites as spam. Yahoo automaticly puts the Google invites in your Bulk Mail folder - so a different address would be the best.
(hide) If you want to play a game with an opponent of a similar level, you can define a required BKR range for a new game invitation. Then nobody with a BKR outside this range will be able to see/accept it. (Katechka) (show all tips)
