1. I have added optional rig names, i thought it may be useless, But if at least one miner need it, here it is
ethminer -G -F http://ethereumpool.co/?miner=[HASHRATE IN MHASH]@[ADDRESS]@[OPTIONAL RIG NAME]
Last parm is not necessary, if someone do not need this he can continue mine with
ethminer -G -F http://ethereumpool.co/?miner=[HASHRATE IN MHASH]@[ADDRESS]
Then all rights will be names as 'rig'
Pool has problems within last night (GMT 0), someone was attacking us with DOS - it's fixed now.
