The KC3 donations button is down. We had to take the page down as someone was using it to test stolen credit cards. We are working with our ISP to rework the page with sufficient security that this doesn't happen again.
This had nothing to do with people who legitimately donated to KC3. None of your information was compromised. It is not saved in any form or fashion on our site.
We apologize for the inconvenience, and hope to have the donations page back up as soon as possible.
