Why doesn't DuoLingo alert you when someone replies to your reply in a discussion? This is really annoying because I have to go back and check to see if they did so I keep having to follow the discussions I post in. Thanks!
It used to do that, but it doesn't do that now for some reason. It's probably a bug, and hopefully it will get fixed soon.
I agree, though. It is kind of annoying (and tedious) to keep checking back to see replies.
For now, (and since the recent forum maintenance), users are not automatically subscribed to discussions they comment on, so to receive email notifications, you need to manually subscribe to any discussion you are interested in by clicking on the Follow discussion button at the top right corner of the discussion page.
I guess that you just have to get used to this... at least have hope that duo lingo is working on it! (It is easy for me to be optimistic though, because I have bad internet connection anyway and am used to these things).
