Full Tilt has a semi-publicized bonus right now -- you may or may not get a popup when you log on (I didn't). It doesn't show up on the promotions page (at least it didn't for me) ...
But if you open the client, look under the 'Requests' menu, you should find 'Check My Bonus Offer'. I got a lower tier offer - $50, no additional deposit required, clear by earning Full Tilt points. Some people on the forums have been getting offered up to $500.
Just when you think bonuses are dead, here comes the Tilt. Nice work peeps.
Too bad I don't play for money.
