A: You can credit an adoption in 2 ways.
1.) Click on adopt a duck from the main page, enter the number from the adoption paper you received from the team you want to credit, enter the number and hit verify. Continue payment process to adopt a duck.
2.) Go to the Teams page and click on the team you want to give credit to, click on the "Adopt a Duck" buttons on that teams page and follow the prompts. You do not have to enter a number. There currently is nothing saying or verifying that your adoption is getting credited to that team, but if you follow the links from the teams page, it will get appropriately credited. An update to this will be coming soon. Sorry for any confusion.
