The Nevada secretary of state’s office has created a new website for voters to “cure” their ballots by verifying their signatures before the ballots can be counted, CNN reports.

Voters have until November 12 to cure their ballots.

Nevada Secretary of State Francisco Aguilar told CNN that curing is currently his office’s biggest concern, and he recently briefed Governor Joe Lombardo on the issue.

“We know the counties are working hard to contact voters in need of cure, but voters can help support that process by ensuring their contact information in their voter profile is up to date,” Aguilar said.
