This week marks Creative Commons’ 7th birthday, and Twitter is helping us celebrate by generously matching all donations made to our annual fundraising campaign for the next week, up to $3,000. Even if you’ve already contributed, give whatever you can today – Twitter will match your donation so that it goes twice as far towards supporting CC.

Creative Commons uses Twitter to engage directly and efficiently with people worldwide who care about participatory culture and the innovation and social good that come from it. Twitter provides a valuable way for nonprofits like us to give and get feedback, promote projects, and announce milestones. If you’re not one of the more than 240,000 people already following us on Twitter, visit our page and become one! It’s a simple way to stay up to date with all things CC.

Here’s another way to support Creative Commons during its birthday week: When you tweet this week, include the hashtag #cc and link to our support page, to let your community know that you value the work Creative Commons does:
