Good Morning All,
Just created an account after lurking for some time and oculd use some help. I am not a developer but more of an entry level web master that hands off tasks and is the liason between our owner and our developers. I do a lot of troubleshooting and testing.
Welcome to the community @giovanni_falco ! I hope you enjoy your stay and create connections that help you in your journey.
Welcome to the community forums.
The best way to start is to ask and try to help other into the forums.
You'll find information on StackExchange too and you can start diving into the http://devdocs.magento.com/ not only for learning but to correct and improve the docs.
We can't forget the powerful User Guide: https://docs.magento.com/m2/ce/user_guide/getting-started.html.
Another recomendation could be to be aware of Magento issues on Github: https://github.com/magento/magento2/issues (if you are technical, of course).
Also, you should read this post: https://community.magento.com/t5/Welcome-to-the-Magento-Community/Start-here-and-hello-from-me/m-p/5... (in particular the guidelines) and if you are not sure about how to use the forum you can read the FAQ: https://community.magento.com/t5/help/faqpage.
If you need information related with GDPR, you should check this: https://community.magento.com/t5/help/faqpage/title/gdpr
Finally, you'll need to get your hands dirty with the platform.
