re: Hackers
You could always sign up for the Ic3 newsletter.
They know a lot of the latest tricks and hacks. Just give them a little personal information and tell them what type of hacks you already know. If you've taken part in any hacks, be sure to include a brief summary and be specific about how you did it. They may follow up with a few follow up questions before bringing you into the fold, so be sure to tell them everything you can. Any Hacker references you can provide will also increase your chances of being accepted.
Good Luck.
