You're a newbie in term of the site so it's certainly more difficult for you to ask these sorts of questions without getting negged.

Just be detailed I suppose, what you are doing, the exploit you are planning to use and the information you've gained on your own from google/bugtraq etc.

And don't ask how to hack hotmail, not for a while anyway

Might be worth recording what you are doing and in the future you could post a wargames tut.
