Currently, you can donate 10 BTC (~ $6,000) to become a "Donator." You can donate 50 BTC (~ $31,000) to become "VIP." I'm not opposed to supporting something that I use free of charge, but wow. How many new Donators/VIP members have emerged since BTC's value surged? And when were those amounts decided?
I believe I read a post that the forum doesn't need donations any more, so theymos probably won't change the setting trying to get more donations.
