Hey guys:

I was wondering if u guys knew about any good forensic challenge sites.
I'm looking for a good one so I can learn more. Not too hard, though.
These are the ones I know already:
try2hack.nl
mod-x.co.uk
hackerslab.org
These are sites that u guys have mentioned that I went to.
try2hack is good, still working on the level 2 username though (lol)
mod-x has me stumped (level 1, I just can't figure it out)
and I still can't access the hackerslab prompt

I'd be very gratefull if u guys could give me some more sites, thanks
