There has been a lot of changes again at the PokerSource site. Following the closure to American players of several of the big poker rooms, PokerSource have discontinued their free bankroll offers at Absolute Poker and UltimateBet Poker. They have also stopped offering the Bodog bonus to US players.
They did briefly add a bankroll deal at Minted Poker for US players but stopped that again quite quickly.
Also, they have included a poker quiz now in their free bankroll application. Apparently it is not difficult at all. They have also added in phone verification to the process.
As the details are changing quite a lot lately it is best to check the site here for the latest deals.
