Jorisss' introduction

Hey you guys, I'm Jorisss, and i'm from holland. I've been playing minecraft for quite some time now, and I don't grief.
I'm a bit confused on the whole 'how to be able to build' thing, what will I need to do next, as soon as I posted this?
Please help me on that. Anyways, my english is pretty good, I have an International Baccalaureate, which means I studied on a bilangual school. I hope you guys let me in, I'd love to play here!
