PP Monthly 10K Freeroll ?

Hello Cardschat!

I have a question for anyone who has experience playing in PP's Bankroll Builder freerolls.

There are 2-3 of these freerolls every day. The top 50 win cash ($100 total prize money) and a ticket for the following Saturday to a $2.5K freeroll. I have managed to win a ticket to this event nearly every week, and have always been automatically registered for the $2.5K Saturday freeroll.

Question 1: If I qualify for, but I am unable to play in, the Saturday $2.5K, can I unregister and play in the same tournament on a later Saturday? I see the "unregister" option available, but I do not want to experiment to see if I can re-register after I have clicked it.

Now, the $2.5K prize split among the top 200 finishers is generous in itself, but what's even better is that the top 200 also get a ticket to a monthly $10K freeroll! I qualified for this third round of freerolls for the first time yesterday, but this has put me into a confusing situation. Yesterday was the last day of the month of February, so I am not sure if I missed my 10K tourney, or if I will be able to play in March (today is March 1). And what is causing me the most consternation is that when I click on "my tournaments", I don't see the $10K freeroll listed (I DO see all the other freerolls that I'm regsitered for listed, however). This leads to my next question...

Question 2: Do you have to manually register for the monthly $10K freeroll, or are you automatically registered like the $2.5K tournament?

If anybody has played in these tourneys at Party and can tell me the answers, I will be eternally grateful!
