I hadn't paid much attention to this before but am interested in supporting, but I am curious, are we still at 10/50BTC given the intent of the original amounts and the current value relative to fiat?
Yes we still are.The rule of not calculating the value of bitcoins in terms of fiat is followed while taking the donator status otherwise it would be unfair for the previous donars.
Having said that,you can always donate whatever amount to the address mentioned in the donate tab.Forum doesn't depend on donations now.
