In regards to the website it needs improvement but the service is fully functional, we have recently spent most of the time improving the bitcoin shopping cart which is essential for selling the service in bitcoins.
Problems we had before, that have been improved, bitcoin transactions were done by hand, the accounts needed activation, customers wanted billing by second not by minute, all this changes have been applied.
