It’s been a long time coming but we have finally fully launched Greek and Polish as supported languages. While the languages have been fully functional for some time now, this means they now appear in the normal language dropdown for all users and are available on registration. This also means avatar outfits have been added along with a LingQ logo with language flag instead of the standard beta logo. There are still additional avatar improvements required but we wanted to get this out there first as we can always continue improving things over time.
Thank you for your patience, all those who have been waiting for this, and enjoy the new status for these two great languages!
