Well, it's a basic 'test your hacking skill' turorial.
but, it's progressive, and has a forum, so if you don't know anything about hacking, and you are willing to put in a little work, you can actually learn some very usefull tricks.
i'd start with the Java Scripts. (it'll help if you have a decompiler other than notepad) from there, logic is pretty easy (although not very hacker related) internet is just down right fun, and when i finish thoes off, i think i'm going to go into cracking. (have to find another copy of visual studio 6)
the challanges get progressivly harder, so for example, on the first script page, you could view the source, and just look arround and find the line where is says 'If Passcode = "secretword" then Href=www.youwin.com' and then happily type in 'secretword' on the frontpage, and get the reward. (a simple code that you enter in to the registered database) if you compleate an entire section, you get a 'gem' thingie that says how great of a (fill in the blank) hacker you are. then you can expand your abilities to other areas. it's pretty pointless unless you are interested in codebreaking, but seeing as how I am, and how I've been doing most of this stuff anyways, it's fun to have an open forum for it. (and i've even picked up a new trick already!)
