Sending Messages to Friends on Duolingo??
I have not been on Duolingo for a while, and now I can't send messages to friends? What happened?
As the others said, the activity was removed some time ago. The worst thing about it was that it was done without any warning so we had no time to exchange some contact information with our friends. It is not known when, or even if, some form of communication on Duolingo will be again available.
