Wikipedia is using Paypal for fundraising. May I
suggest that
www.sozialbank.de has a very convenient
system for fundraising and probably would accept
Wikipedia foundation as a customer?
Sozialbank is a bank especially for non-profit
institutions and would be much better suited for
a convincing foundraise of a non-profit.
At least for european customers they should be able
to offer a web interface where money transfer is
possible immediately.
