He means getting the new account bonuses and activity bonuses that poker sites give. If you join via the links on this site you get US $100 free money from Party Poker when you become a 'real money' player. That buys you quite a bit of practice!

The only thing is that there is a time limit on how long you have to play the number of raked hands to claim the bonus, so don't join as a real money player until you have enough time set aside to play a fair bit for a week or so.
