I have the book "Sheep or Ship" in pdf.
We can create a Whatsapp group to exchange knowledge about Phonetics and Phonology.
For me, these areas are the most important when we want to start to learn a new language, and even to know more about our native language.
Phonetics and phonology are, in my opinion, the most difficult feature of English language. I recommended a book called "Sheep or ship" to put it on practice. Also, I'd like to join you both to practise.
