Toribash got me new friends and the fourms has a nice community that helped me when I was a newbie. They inspired me to become a better person in this community.

The biggest benefit was to practise my english. I live in Turkey, so the english education isn't that promising.
The community made me become far more creative too, the replaymaking, the troll stories, the rpg's etc.
One other thing I learned, was how to use gimp. I might not be quite there yet, but I've learned the simplest basics, which I wouldn't normally learn since I don't need it as much as I do in this game.

The biggest benefit from me was leadership from leading clans and org's.
also how to handle money an how to market.
And I have made friends online, but who knows if that will come in handy.
