Roxy, Jeff, and Ricky continue their own efforts to raise awareness about organ donation.

"A lot more people are more comfortable looking into it and going through with it," Ricky said.

Jeffrey can’t thank his wife -- or donor -- enough.

"So grateful. I love them both so much," he said.

"They're family now. I got some new family members out of it," Ricky added.

Some of those who doubt Facebook’s current effort will work believe it could work if the site kept the issue fresh in users' minds every day. Transplant experts recommend real-time Facebook updates on the growing number of registered donors in every state, allowing donor registries to advertise for free on the site, and the development of an annual day to celebrate registered organ donors.
