Hah, so you've found at least something.. The challs 
stop here for a moment, I'm gonna make some where you need shellcode 
and stuff, if you feel like brainstorming about some cool (and only 
difficult) challenges, then pop in on anondox.com irc and pm me on 
there!

About subdomains:
If you want a subdomain you have to pm me on anondox (see above) so
we can discuss this.. Only serious projects/friends/opensource can
request such a subdomain.
