WhatsApp audio-video lessons on the go

 I just discovered that if I make a video on WhatsApp directly it is much clearer and the audio is much better than if I make a YouTube video which I then have to download to the WhatsApp group.  I call my videos "audio videos" because they're designed for people to watch as a video but then also to listen to when they are on the bus or driving a car etc.. Over the years I have created hundreds of lessons some of which you can review on pumarosa.com.  This way all I have to do is sit in my chair in my room while I'm drinking coffee and record a lesson and send it to everybody. To be efficient I'm going to create WhatsApp groups specifically for lessons so that there is no chat. For example lessons on basic vocabulary, pronunciation and verb tenses.
