I'm a beta user on money.stackexchange.com (still in private beta). I was also a member of www.BasicallyMoney.com, and had asked and answered many questions on that. Does that count toward my commitment or do I have to answer 10 more (I'm out of fresh questions)?
My guess is, they will want to 'revitalize' the site with lots of new users with new questions. Thus, they will want you to fulfill your commitment 'again' essentially.
