Official Guide to Party Poker Rakeback

[prunch]

o.k so ive read every single thread on PP that I could find and it seems that no one actually is 100% certain what is going on. All I seem to hear is conflicting ideas about rakeback, especially regarding the sit n go's. Is there any one who can say for certain what is going on? If I have a party have account already set up without rakeback but would like to set up a new one what would be my best course of action? any help would be great, cheers
