According to Michael W. Carroll, Associate Professor of Law at Villanova University School of Law, the Creative Commons is in danger of losing its charitable status with the IRS unless it receives more donations by the end of the year. Any donation, no matter how small, will help and it will be matched. For donations at $50 or above, the CC offers buttons, stickers, and shirts (at least $75 for this item).
