According to the info box in the lobby: "Invitational tournament for players affected by FF500 promotion issues"
I have no idea what they are referring to, but there always seem to be issues with PP software. I'm looking at it as "compensation for getting screwed because there was no late reg for today's CC buy-in" or "compensation for one of the several tickets I spent hours playing for that expired before the stated date", or "compensation for that tourney a month or two ago when I got disconnected every few minutes".
