Impactful question . . . .
When activity was removed, it was said that it would eventually return, even possibly with a private messaging system? Duolingo has been virtually useless for me, without the amazing support and encouragement from my friends, and I would love to know when it would . . . or will be back again. Thanks,
Hi Ashley! :-) There's no indication in the least at when the "much better tools" Mr. von ahn promised are going to be implemented. The closest he came to mentioning the time was "soon", as you may see in (Warning, heavy discussion) the official announcement. As far as I know, no-one asked him about it in his latest Reddit AMA.
In the meantime, keep learning, and remember that heroes don't always have company.
