Can't Post Score to MagMic – Magmic Daily Sudoku Review

I have been playing Sudoku on my BlackBerry since May of 2006. I chose the iPhone because it advertised MagMic's Sudoku and I didn't want to lose it. But I can't find any way to log into the MagMic user pool or to post my scores to the leader board. It's all very well and good to be able to compete against the leader board, but you can't get on it if you can't post your scores.
