@iscarlosmolero I'm a new GNU/Linux user, just 5 months. I'm sharing my enthusiasm here, with blog posts and have set-up #Endof10 project at our little library in a nearby town to help folks upgrade. Doing a "Intro to GNU/Linux" presentation next month and offering training on using Free Software like LibreOffice, etc.
So, my answer would be organize a project and volunteer. Libraries are a great place for this.
