Almost every month, Mission:Libre holds public meetups on Jitsi (video conferencing) where people of any age can come and get updates on Mission:Libre's progress , ask questions and discuss how we can get teens in to free software and why doing so is important
These are meetings open to ALL AGES to find out more about the Mission:libre project, it's goals and aims.
If you work with young people I would strongly encourage you to try and attend this.
Free software is more than about the four freedoms that give you the right to use, share, modify and study the code, This allows us to contribute and take control of the software we use and build the software and services we want.
