Hi Neoncube,
I just started today, trying out this site, so I thought I would start with the lv 1 official Polish course from Memrise (which I have done zillions of times on Memrise). I'm doing the courses from English to Polish and there are a few words so far that don't have the right Polish translations. For example, "No, thank you" should be "Nie, dziΔkujΔ", but it shows the answer as just "Nie". There's another one so far like that and possibly more, that I haven't gotten to.
I appreciate all of your effort going into this site, with the fact that Memrise has decided to pull the plug on the old format and the community courses. Thanks very much. π
