I'm guessing you guys are Brazillian, right?
You have an option by buying pre-paid cards and using it on Paypal. You can acquire one of those right here. They'll serve as credits for your Paypal account, and you can use them to donate to the server.
Yep we are. We knew this system, unfortunately it have a tax on it.
You'd also have a tax if you made it directly from PayPal with an international card, although the full transaction price would be roughly 10% lower than the current pre-paid option. But, unless one of you guys find an international card to use, that's the only viable option I'm aware of until they start accepting something like Neteller.
