How can I donate in dollars?

Heya, I've been enjoying my time in this server for a long time and I want to help it grow (and also i want to skip the damn queue lol).
But seeing the donation options there is no USD option to donate, is there anyway to change this? I saw the forum in FAQ about donations and in the image the numbers appears in USD.

Currently I'm not playing on retail neither I want to help grow this shell of Blizzard we have these days, specially since the Warcraft 3 Refunded fiasco

You don't need to change to USD as far as I know. I donated with USD instead of Euros and it worked. It was like 11-12 dollars for 10 euros.
