628208 10/16 I tried to donate $75 but once I had completed the information, the system wanted me to "log in". I was unable to log in. I ended up trying to create an account and getting an email from mini-wikis or some similar name related to wikipedia. I do not wish to join or log in, I was simply trying to make a donation.
This was an Ingenico donor, who eventually succeeded: INGENICO 000000657040023523390000100001
