Well, lately I have been talking to ROMMAN, and it seems that they have some problems with the server. They are currently checking the situation.
cory1492 an active poster in this blog posted some screenshots on the current situation with the supercard site.
This first screenshot was taken by cory1492 when no proxies where used i.e a normal internet connection outsied china.
This second screenshot cory1492 took it when he was using a chinese proxy to access the supercard's site.
Further updates will be published to keep you informed. In the meantime if someone just encounters some new information just post in the comments here.Thanks!
