What's this Poker Players Alliance party wants us to join?

In response to my own question, I sent them an email inquiry on the subject. Will post response if/when received.

Also, I'm getting the impression that the only hassle-free way to deposit for this bonus is to make yet another (different) deposit at Party, click on the link in the popup that will then appear, and join PPA right then and there. Is this true?
