I enjoyed your guide. I've just started gpu mining. I know I'm too late to the Bitcoin party and I've spent a little time on Litecoin, though I think I may be too late there as well. I've been searching for other cryptocurrencies to dive in to and I think I'll give the Quark a shot.

Can't remember where I saw this.
Copy/paste this code into dogecoin.conf file in the wallets' folder.

rpcuser=doge
rpcpassword=wow
addnode=67.205.20.10
addnode=162.243.113.110
rpcport=22555
server=1
daemon=1

Is this the same as you have used?

I'm also mining them because I can actually get some. I'm trying to mine Litecoin as well, though I'm not even close to having 1 coin.
