Show units of discussions' origin
I was looking through new German discussions and came across this: http://duolingo.com/#/comment/315364
This is what it looks like for me: http://img17.imageshack.us/img17/4820/screenshot79931651.png
Apparently the author posted this discussion in some learning unit, but there is no way to know which one it is. Shouldn't there be some path to this unit? Like: German → Plurals or other unit.
