Get a VPN, connect to USA and you will magically be able to open a Nova account.

At least my test on that worked last night.
That still won't do the trick for me. The registration interface comes up, but once I enter all my details, I receive the standard error message
"We are currently doing maintenance on our registration tool and will currently not accept any new users. Welcome back later!"'
I've been seeing this message for weeks now. As far as I know, Nova has disabled new registrations after being hit by DDOS attacks.
I hope they'll come back up soon because Nova features a few coins I want to trade exclusively.
