"PartyPoker.com announces the brand new $50,000 Party For Free freeroll tournament running September 1-18, 2005, with a first-place prize exceeding $10,000 CASH.** The grand finale is Sunday, September 18, at 6:40 p.m. EST. There is no cash buy-in for this tournament! Use your Party Points to enter one of the daily qualifier events or buy directly into the Big One!"

I see over 400 people already registered and was thinking what is the maximun number of players since it will get it for sure.

If its something like 2500 i wont even bother registering. If its around 2000 i wanna reserve my seat.
