All you must do, is download the craftbukkit jar (google) and create a batch file (I really had difficults with that!). I'm trying to explain you: create a file with noteblock (or whatever it's called, I'm Dutch), type in the text you can find on craftbukkit wiki under the tab setting up a server. Now you choose the option save as, and you type after the file (call it 'run') .bat . Then you see the option save as: text document (.txt). You click it and select 'all files'. Save, and run your batch. Now, it won't work, because you have one thing left: rename the jar. Doesn't matter how. Only forward a port (comment when you don't know how to) or use hamachi (comment when you don't know how to). Greetings, Black Link 19 PS. When you want a cracked, open the text from the batch file and replace true with false.
