Thank you. We appreciate your interest and input and look forward to others.
Dear Jay, it seems that in Duos' effort to improve the lessons you are actually making them more confusing. Apparently the computer version is becoming more and more nessesary to use Duolingo rather than the phone. Example among many; At these early lessons is it really important that the normal καππα audio now include the κι audio to confuse us? Ελλινικα is now also ελ? Common, this is the alphabet level for crying out loud!
