Welcome to the community forums.
Your user seems to be working right.
The best way to start into the forums is to ask and try to help others.
Also you'll find a information on StackExchange and you can start diving into the http://devdocs.magento.com/
Another recomendation could be to be aware of Magento issues on Github: https://github.com/magento/magento2/issues (if you are technical, of course).
Fianlly, you'll need to get your hands dirty with the platform.
