I got the number error when I wanted to create a new chain with 6 blocks per hour and 50 coins per block. On the old site it worked to just enter 50.0 and 6.0 instead. On the new site that doesn't seem to work.
Still cant reproduce.. but i will try to change the validation tomorrow morning again... strange.
Maybe it would be a good idea to have users pay "electricity fees" for their rigs. It makes things more realistic and it also solves the problem of everyone just buying a ton of rigs right from the beginning because you could make a loss if you aren't careful. If your balance reaches zero, all your rigs would automatically be turned off.
The idea is good.. but what should i charge? Could i possibly drain on the submitted BTC? Thats not what i want (dont want to impose fees that arent really neccessary..). I have prepared a global maximum on hashing capacity that people will be able to rause in future with donations.. its only prepared atm and not yet decided upon. But electrical fee has some appeal..
