I will soon add mail confirmation adjustable for everyone, not a system wide setting.
Currently a lot of people want it and a lot of people don't want it..
Is it normal for hashrate to fluctuate this much ?
I'm running 40mh but see
0, 8.95mh, 26.5mh, 35mh , 45 and sometimes higher
At many times I'm not sure I'm actually mining
I'm currently trying to get the orphan rate lower by retargeting the workers faster/slower...
My testing is finished soon.. I guess with 12s block target its simply "normal" that there are few more orphans than with "normal" coins..
Orphans and hashrate fluctuations @ https://eth.suprnova.cc fixed, Vardiff coming today
should I use for eth.suprnova.cc 
Vardiff kicking in already?
You don't need a --diff-multiplier here, take a look at the getting started page, you simply have to put in your hashrate:
