In 2012, MOSAIC pastor Hank Fortener started a non-profit crowdfunding site to assist families adopting children from both the U.S. and abroad.
Hank's site, AdoptTogether.org allows families to crowdfund their adoptions using their existing social networks.
Over $4 million has already been raised. Now Hank and AdoptTogether's hope is to keep the momentum going with a day to celebrate adoption all over the world.
To mark the day, Hank has requested that everyone post a symbolic photo to social media: a smiley face drawn on the palm of one hand.
Former NBA player Jason Collins and countless others have pledged their support for the effort.
