To share your sustainable actions with friends through Facebook or Twitter, you need to have your account connected. Begin with finding the action you want to share. Select the Pin, then tap "Buzz". A new page will pop up and give you the ability to fill in a caption, and take a photo of your action (button in top right corner shaped like a camera). Once you have a caption and/or photo, tap on the social media site of your choice, found to the left of the "Buzz" button. Once rethink/ is allowed access to your Facebook or Twitter accounts, it will post to your page when you hit "Buzz" again.
