Thanks for the info. I've been using the same coin address. Does this mean I've been wasting energy/time?
Do I need to create new account for each computer, or can I just use getnewaddress on the same account to get another coin address?
If I need to create another account, do I need to put that information on the primecoin.conf as well?
rpcuser=account1
rpcpassword=password
rpcuser=account2
rpcpassword=password
rpcuser=account3
rpcpassword=password
