Yes, the problems lasted during an hour or so but after that everything worked fine
Not sure what happened there, as we were not doing any work on the server, probably a traffic spike :/
Thanks for the reports.
The accum display will be very inaccurate even after we fix the issues with it, and yes, there are some major problems right now.
The premium price is sadly not a joke - we've honestly converted the BTC price into accum, and that's what we got. It's a bit disappointing, but I guess the thing is, you can't earn that much with webmining. Having a great CPU would help, though.
Regarding the rest of your ideas - I think there are some pretty interesting ones, we'll discuss them :)
