How to get back a friend deleted by accident?
I recently deleted on of the duolingo users who I was following. Does anybody know how I can add her again without using Twitter or Facebook. Where can we find a list of the duolingo usernames if we wish to choose users to follow?
You can search for users by filling in their name in the top right corner. You can also click on a user during a discussion to go to that person's profile page. If you're at someone's profile page, you can click the "+ Add friend" button to add that person as a friend.
