Update at Stein's site: the recount costs for Wisconsin have been raised and the target has been increased (by $2 million) to raise the money needed for the Pennsylvania recount (which has the next deadline).

The linked page on Stein's site also now has a little more information on the costs involved (in addition to the filing costs) and how they arrived at the fundraising targets they've set, as well links as two state Green Parties that you can donate to in order to increase your support. (Although I doubt many of us are quite that wealthy....)

(teaotter,do you want to update the post as the fundraiser progresses?)
