Social media and online platforms at the service of catechesis, training and teaching: the idea of creating a small and agile manual came to mind of Marco Pappalardo, journalist and teacher (and, I say this with pride, also and above all a friend! ), which involved me and Alfredo Petralia, expert in applied informatics, IT consultant and social media manager in this project. Thus came out, published for the Paulines, "WITNESS THE GOSPEL WITH YOUR LIFE: GO ON THE NET". I dealt in particular with the chapters relating to the YouTube channel, the Newsletter and the management of whatsapp groups. In short, I played at home, leaving the hardest work to my two traveling companions. In the book you will find ideas, tips and suggestions for activities, along with contributions from some experts.
