seems to be very naive,... But why can't I access to my club from the P.C.?!
You could do so, if you would install an Android emulator on your computer.
Right now, I can't find my own thread about Windows emulators and one recent thread about Linux.
Maybe you find it for yourself with the typical keywords like site:duolingo.com Android, emulator, my name, etc.
They are probably not indexed already.
