Hi all its good to finally say hello. I am afraid though that this is really a precursor to asking about a problem.which I'll get to in the appropriate way. Anyway my name is Nige and I am supposed to be the web admin for the company I work for (I drew the short straw) in Derbyshire UK and we use Magento for eCommerce solution.
Welcome to the community forums.
I guess the best way to start is to ask and try tohelp into the forums.
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.
