Doing free projects is a good learning experience, plus they never get to harras you about deadlines, bugs etc.
If you are just starting out in PHP programming, a project like this can help you get some experience, plus your name ends up in the credits.
I'm not sure how this will affect your career, but for doing free projects has gotten me quite a few well-paid contracts in the past.

But ofcourse, asking for an ASP programmer in a PHP forum is punishable by mau-mau.
