Just used two different VISA credit cards (2 different banks) to try and donate $10. Both were denied. That has never happened before. You might want to check up on it. I did it from my new HP Pavilion and suspect Microsoft is screwing things up again. But no way to know. If you have suggestions, I’ll try again.
Thank you very much for your mail and your wish to donate, and sorry for the inconveniences!
We had to take several anti-fraud mechanisms to prevent abuse of the credit card donation means. We cannot directly control these, as the payment occurs via a service provider. I assume that one of the anti-fraud mechanisms kick in when you donate, which is why the payment is refused.
I am sorry for that - any chance to use one of the other donation options listed at http://donate.libreoffice.org?
