It would be helpful to have a note for people who speak English as a foreign language wether their recording is welcome or not and why.
(And if not, allow them to indicate their native language in addition to entering their e-mail address so they can be invited back when their language comes up)
If you follow the path laid out by the sidebar, i.e. Home > Speak > Listen > Profile, you record sentences before reaching the “Your English accent” part in the profile section.
In that section there’s no option to mark your native language in addition to your accent. As a non-native speaker, this left me wondering whether I should not have recorded anything in the first place - so probably other non-native speakers will wonder about that as well.
