just note that in the getting started part of cann.suprnova.cc it says that the address is stratum+tcp://canna.suprnova.cc:4442 It isnt. its stratum+tcp://cann.suprnova.cc:4442 , and the also is x11. soo someone will need to change that. i have emailed them though.
It looks like "cann" and "canna" addresses both work exactly the same. Am I missing something here? Or is it just a typo?
