hmmm, noone knowing what the donation is used for?
then i guess its simply some extra benefit to the pool-creator without any certain intent?

another one: the suprnova-website (-> getting started) states that anonymous mining is possible by specifying a (ZEC-)address as username.
mining statistics should be further available through https://zec.suprnova.cc/index.php?page=anondashboard&user=

i've tried to do so but all i get is a dashboard-page where all values are missing even if i have submitted multiple shares before (no balance, no workers listed, empty histograms,...).
the address used also has not yet received anything so i guess there is a payout-threshold? if yes, how high is that, if no, how does one trigger a payout for anonymously mined ZEC?

again, thanks for your help!
