I use it, i was attracted for the PayPal thing, but stay for others reasons such as, personal attention and good prices.
I must warn you the volume is not high so, if you need to do big transactions maybe this is not the place for you... yet.

I' having some problems to log in, 
When i go to https://cryptonit.net/main?destination=main its says "web page is not available" like if the site was down. The same thing happen when i try to contact support.
Is there a social network or some place were you inform when the site is down?
