I intend to add new, cheaper donator ranks. I won't decrease the price of the old ranks, though I may rename them (to "Donator+" and "VIP+" or something like that).
Senior VIP maybe?
Are the new ranks' price going to be variable or adjusted every x days or months depending on BTC price?
What do you think about pegging the price of the rank to something more reliable than a fiat currency but less volatile than BTC? I saw one guy here couple of months ago selling his ebooks for BTC pegged to the price of gold (don't remember the exact amount).
