There's already been so much discussion about this it's uncanny. You should have searched before posting and you would have realized that the donation amounts were back when it was to keep the forum running. Now with ads they're not necessary but since it is a Bitcoin-based forum, the prices stay the same, in terms of Bitcoins.
And don't beg.
I didn't find any recent topic about it. I didn't want to revive something dead... I removed the 'begging'... it wasn't really begging.. I didn't think anyone would do it lol
