May i ask you a dump noob question?
You are telling not to use "--no-submit-stale" im not sure how to check if i am using this. Would it be wrtitten in the cgminer.config if i do?
Hmm, yes, if you used it, then you are using it, and if you didn't then you are not using it. It would either be on the command line or in the config, if it's not you're ok.
And while mining on your pool, I am getting a lot of notifications about " Network set to ..." "Stratum from pool detected new block"
On other pools i get almost 95% "Accepeted..." notification and only 5% the other, on your its different 95 % the notifications written above and only 5 % about accepted...
is that a problem at all?
im using the europe server with two rigs on one worker
What's your hash rate? If it's low, this is a somewhat high difficulty pool you may get less accepted but they are of "higher value". Ultimately, watch your balance and payouts, and if they match your expectations/calculations, you're good. Give it a good day or two before you decide.
