Question: How do I own some internet fuck legally?

Hey guys..
You might have seen my thread the other day about a hijacked domain - finally got it back, with much help from Sedo and Namecheap.

I've been inconvenienced enough to want to take this further - but don't have much experience w/ the legal side of things - and GFY is full of lawyers ;)

Summary:
-User installed custom backdoor / trojan on my machine
-Captured my email password
-Downloaded and then deleted 70,000 emails

-Used passwords from those emails to access my namecheap account and transfer some domains of his choice to his own namecheap account
-Proceed to list the domains on Sedo for sale

The domain brings in / brought it a decent income, and obviously that's fucked, not to mention the intentional deletion of all the emails etc.

From my logs, I think the guy is in Ontario - I'd love Sedo / Namecheap to provide real info about the guy, but I'm not sure if their privacy policy allows it without a subpoena.

So what do you think.. worth taking it further? I'm in the US for a month now, I could have the chance to execute some proceedings I guess.

What's the proceedure for those who have been there :D

Thanks!
Simon
