Fenway has to accept the payment. Probably just hasn't gotten to it yet. How long ago did you put it in? Also, did you add a note to the payment indicating your screen name so he would know who to credit?
Mike is a busy busy man...give it a week then start asking questions. It took mine about 4 days and that was a while back. But to be sure you should send in $10 everyday for the rest of the week!
