Help me, please
Where can I invite my friend here?
Ok all you have to do is go to your home screen. On the right hand side, under the box called French progress is a box called leaderboard at the bottom of the leaderboard box there is a button that says 'send invite' Click that and type in your friend e-mail address. A message will be sent to them inviting them to join Duolingo. Hope this helps. Good luck.
