I think that I would like to set one of my S3 to solo mine just because.

What is the code or changes to the user interface is needed?  When I try to enter my node IP and port, username, and password, all I get is 'dead'.  I think that I need to add the "--btc-address [address]" option but can't via the normal S3 interface.

I'm running a full node with:

server=1
listen=1
rpcport=8332
rpcuser=user
rpcpassword=pass
rpcallowip=192.168.1.200
