My ten-year-old and his best friend had a Minecraft-LAN today (with a lot of help from me). Since it were our first experience of a LAN with more than 3-4 players I set up most of the stuff. But next time I will involve the players a bit more. I think its an excellent opportunity to educate them in a range of different areas of digital medias. Basic IP and network stuff, basic hardware, basic online hazards, social media netiquette and also a bit of coding.
