Dolby, you don't have to share your PIN. Initially you'll probably select 'Random Game', which will either look for open random invitations, or, if there's none there, issue an open invitation for the next player. Once you've played a handful of games you may know a few users who you'd want to play again - then you can just say 'Join Game' and enter their user name. The game is still quite young, so the userbase is not that big. You get mainly two kinds of users, the ones who play 'on', meaning they start a game and want to finish it right there and then, and the ones who play 'off', like some kind of snail mail scrabble. (I am the latter kind). Some of the first type don't have the patience to play with those of the second type and may end games prematurely. There is still a lot of refinement that can be done with this game, and the developers seem to be on top of it, but it can be fun in the current state.
