I think I am on duolingo's website and I look over at leader board. I click on someones name to talk to them but it will not work. Any one know what to do?
No they removed the activity streams about a month ago. There is supposedly something being created to replace it In the near future. Meanwhile many users are using discord to communicate I can give you various invite links depending on the language if you're interested.
Near feature? Wait-You seem to know something... XD. Do you have any idea what's gonna happen?
No in fact from what Luis said in a recent AMA on Reddit I don't think they are planning to bring back a chat feature but will focus on developing chat bots instead.
