Another newbie question :-
I want to mine on a 2nd PC, can I get it to mine to the same wallet ?
I have tried with the same batch file as PC1 but I seem to get loads of 'Stratum requested work restart' messages
Thanks again

Yes you can mine to the same wallet.
Just add this line (without quotation mark) "miningaddress=walletAddressThatYouWantToMineTo" to your hodlcoin.conf file in your ....AppData\Roaming\HOdlcoin folder.
The wallet should mine to whatever address that you listed.
