On Saturday, Facebook began showing users how to register to vote at the top of the Facebook, Instagram and Messenger apps. “These notifications take them to the relevant page with their state’s official website or one of our non-partisan partner organizations if online voter registration isn’t available in their state,” the company wrote. It promised to show those notifications through September 25th. (Voter registration deadlines vary widely from state to state.)

Facebook has been criticized during this election cycle for allowing lies to stand in political ads, when other sites like Twitter have banned political ads altogether. Earlier this month, however, CEO Mark Zuckerberg expressed concerns about the risk of “civil unrest” after the election and vowed to take measures to slow misinformation. However, critics have noted that it continues to flourish on the site despite the company’s efforts.
