The new option was announced Tuesday by Facebook CEO Mark Zuckerberg to boost the number of potential organ donors. It allows Facebook users to add organ donor along with other personal information on the site.
Donate Life America, the group working with Facebook, said more than 100,000 users had added their donor status by Tuesday night.
The feature also provides a link to state registries so people can officially sign up to be a donor. By Wednesday morning, 18,000 Facebook users had used the link.
But a spokeswoman said they don't know how many of those 18,000 followed through and registered.
