*biep* wrong

How can you "break" something if you know shit about it? It isn't like ooh i'll take that sledgehammer and start smashing it into pieces.

So as sais before, start learning about protocols, the basics about networking etc. Then you can start experimenting with that. Oh and if you want to start playing around and you're afraid on breaking some rules, i'd suggest you start collecting some computers so you can set up some nice lan you can play with all you want.
Never argue with fools... They will only drag you down to their level, and beat you with experience...
