Yes, This project looks abandoned. There is nothing alive any more. I tried to send mail to contact also but no answer.
The only known contact is the Coppercoin user here and he/she is relatively silent. Ive asked on multiple occasions how to help the community.
Is there a way we can keep the project going without him? Seem like mining is working OK, the big question is staking (when, how, where?). Maybe someone more technologically savvy can review the code and try to figure things out?
