There is a new app in beta for Android devices (sadly only Android, no iPhone and no web app yet) that is being positioned as a simple way to allow native speakers of any language to teach their language to others.
I'd really like to encourage any native speakers to try this out. It's meant to be simple teaching tool "for regular people". Here is the YouTube video from the creators:

You can listen to someone's recorded exercise

and then add your own recording to get suggestions and tip from others.

Adding your own mini-lesson is really easy. You just fill out the form and press the button to record your own voice.

You can either make it public or just for your followers. Either way you'd want to let your followers know.
