The new homepage indicates that PokerStars will no longer allow real money players from the US.
Pokerstars has reached an agreement with the US DOJ to allow current players to cash out their accounts.
US Players will be allowed to continue to play on the site for play money only.
They list a link to create a new play money account and download a new play money only application.
They also have a link to a Frequently Asked Questions page.
